A bump on the arm: possible causes of the appearance. Lump on the wrist

The most common diseases that are accompanied by subcutaneous bumps are:

1. Lipoma. The tumor is formed from adipose tissue. The bump is painless, has the same color as the skin, when palpated, a dense formation is felt. As a rule, a lipoma is a benign tumor and does not bring discomfort. Such tumors occur with metabolic disorders in the body. Statistics show that women are more susceptible to this disease than men.

2. subcutaneous cyst. The symptoms of a cyst are the same as with a lipoma, the difference is periodic inflammation of the seal. In some cases, the contents are released from the cone.

3. Hygroma. This seal in the form of a ball under the skin does not cause almost any discomfort, except for a visible cosmetic defect. Most often occurs on the arm under the skin on the wrist or palm. It is an accumulation of liquid and, under any mechanical action, can burst by itself.

4. Fibroma. A benign tumor that does not, does not protrude much above the surface of the skin. Fibroma occurs after injuries, inflammatory processes, may be associated with a hereditary factor. The seal can be soft to hard, and the color of the bump varies from brown to red.

How to treat bumps under the skin quickly and effectively

Many people wonder, can bumps under the skin in? The answer is unequivocal: in no case should you try to squeeze out, pierce or act on it in any mechanical way. If a defect is found, contact a specialist. To begin with, visit a therapist, and after that a narrow specialist: an oncologist, surgeon or dermatologist.

Some seals go away on their own and do not require treatment. For example, lipomas are removed when they become a visible cosmetic defect, and the doctor may recommend not touching a small cyst at all if it does not cause discomfort. If the cyst becomes inflamed, then special injections or surgery are prescribed. Fibroma and hygroma are removed surgically. If the bump is associated with an infectious disease, then first you should undergo a course of treatment aimed at eliminating the problem.

If you find a bump under the skin, be sure to consult a specialist. Only he can finally exclude or confirm your fears, explain why under the skin, prescribe the right treatment.

Sometimes you may see a lump or hard lump under the skin. Most are harmless, but some can be painful and irritating. These bumps can appear on any part of the body.

Most seals are harmless and not a cause for concern. However, in rare cases, additional diagnostics may be required. This happens with cancerous tumors. Benign balls under the skin have the following symptoms:

the seal grows slowly and is not painful;
soft texture;
located in the superficial or fatty layer of the skin:
mobile, you can feel it.

On the arm or leg

Most bumps and bumps under the skin are harmless and go away without treatment. But for the correct diagnosis and elimination of the main causes of their appearance, you need to see a doctor as soon as possible.

A dense ball on an arm or leg is most often a lipoma (wen), fibroma, or cyst.

Lipoma- a relatively soft seal, consisting of adipose tissue, which grows slowly.

fibrolipoma or fibrous lipoma is formed from adipose and connective tissue at the same time. The lower the percentage of fat in it, the harder it is.

Fibroma on the toe and sole of the foot

Fibroma- hard small subcutaneous induration, consisting of connective fibrous tissue.

These are all safe formations that gradually slowly grow.

Cyst is a sac under the skin filled with fluid (usually pus). Its main difference from lipoma and fibroma is that they are located deep under the skin, and the cyst is closer to the surface. All of these seals usually do not require mandatory treatment, but sometimes require surgery to remove.

A lipoma, fibroma, or cyst may also appear on other parts of the body. In addition to the arms and legs, they often form on the back or chest.

On the face

The causes of the appearance of seals on the face, not associated with injuries, are likely to be:

Mumps (mumps) is a viral infection that mainly affects children. Seals will be associated with inflammation of the lymph nodes of the lower face;
Allergic reaction - causes swelling in the deep layers of the skin;
A tooth abscess can lead to swelling in the jaw area.

Enlarged lymph nodes from mumps (left) and swelling of the face due to a tooth infection (right)

In the groin, on the thighs and buttocks

The appearance of hard bumps in the vagina, on the inside of the thigh and on the buttocks can be caused by the following factors:

inflamed inguinal lymph nodes, which is a sign of infection;
cyst - a harmless formation filled with fluid;
abscess - a painful collection of pus;
genital warts - refer to sexually transmitted infections, and are fleshy growths;
hanging moles or warts.

Hanging mole (A), abscess (B) and genital warts in HPV (C)

On the knuckle or wrist

A subcutaneous dense ball or bump on the wrist or on the finger joint is most often a hygroma - a type of cyst that forms around the joints and tendons.

Hygroma (synovial cyst) is a rather soft, smooth ball filled with a dense jelly-like liquid. The causes of its occurrence are unknown, most often it is associated with aging or damage to the joints and tendons.

Hygroma appears near the joints

If the hygroma does not cause pain and anxiety, it can be left or cured on its own, but to remove it, you need to visit a dermatologist. Although often after removal, the problem may return over time.

Small hard ball under the skin

A hard ball under the skin may be a fibrous lipoma - a mobile seal consisting of adipose and connective tissue that grows. An ordinary lipoma (wen) consists only of adipose tissue, therefore it is softer. And fibrous - more dense due to the connective tissue. Sizes vary from a pea to several centimeters in diameter. Lipomas are safe.

If the ball turns out to be not a lipoma, then most likely it will be a cyst - a sac under the skin filled with pus. They are very similar, but the important difference is that the cyst will be closer to the surface and usually goes away without treatment.

Large flat lump under the skin

The appearance of a seal under the skin of a large size is a concern for most people, many consider this a sign of cancer. To minimize complications, you need to pass a series of tests that will help determine the cause of the appearance of such seals.

If the neoplasm turns out to be malignant, then a course of radiation and chemical therapy or an operation to remove cancerous tissue is necessary.

Hard painful area under the skin

An injury or infection can cause a hard, painful area to suddenly appear. Moreover, with an infection, the skin around the seal will be red and hot to the touch, and the injury is accompanied by swelling and hemorrhage. With improper treatment, an infection can be introduced into the wound, and then redness and fever will be added.

Hard balls under the skin due to ingrown hairs

Under certain conditions, not the entire hair is shaved, part of it remains under the skin and cannot break out, therefore it bends and grows inside the hair follicle. This is how ingrown hairs appear, they cause inflammation, pain and form small hard balls in the shaving area. Most often this is the back of the head, and the area. Sometimes an ingrown hair can become enlarged (cyst) after infection.

ingrown hair

Anyone who shaves, uses tweezers or depilatory wax can experience similar problems. Such “bumps” often go away on their own, but they can also sometimes be helped when the hair is already very close to the surface.

The appearance of a dense ball on the skin after an insect bite

Bug or spider bites can also cause swelling and hard bumps on the skin. Most insects are harmless, but there are a few poisonous individuals whose sting penetrates deep under the skin of a person, and their poison is dangerous.

Signs of a bite from a poisonous spider:

severe pain that begins about an hour after the bite;
abdominal cramps (with a black widow bite);
heavy sweating;
swelling and fever in severe cases.

Pimples have turned into hard balls

Pimples are places where the skin becomes inflamed. They appear when dead skin cells, sebum and bacteria clog pores, forming hard balls. Acne (acne) is a common problem among teenagers, but it can appear at any other age. Under the skin, bacteria multiply rapidly and this leads to the appearance of new acne.

Acne comes in many forms: pimples, papules, pustules, cysts, or nodules, so there is no single treatment for acne. In severe cases of the disease, tablets and topical treatment are prescribed.

If the acne is large, then laser and phototherapy, drainage and steroid injections are performed to reduce swelling.

Thickening under the skin after vaccination

Vaccination is a reliable way to protect against infections without causing serious side effects. But some children develop various symptoms after vaccinations, such as:

fever within 2-3 days after vaccination;
redness at the injection site;
a tight area at the injection site (in this case, a cold compress will help);
the rash in the form of red dots may cover the child from head to toe, but it is safe and will pass within a week;
in rare cases, the entire vaccination area may become red, swollen, and hot (an anesthetic and hydrocortisone ointment will help).

As a rule, bumps can occur anywhere on the body. That is, seals can grow on the face, legs and arms, on the buttocks, back or abdomen. Most often, the growth of a neoplasm under the skin can be seen only after a certain period of time, when the bump reaches a large size. Seals grow especially slowly on the scalp, where it is quite difficult to notice a bump if its growth is not accompanied by pain. Most often, like this, without pain and corresponding symptoms, the growth of cones occurs, which are benign neoplasms under the skin or on it.

If bumps or seals cause pain and discomfort, then, most likely, such a problem is simply a consequence of an infection that has got under the skin layer, for example, through the hair pores. As soon as an infection gets under the skin, it begins to develop rapidly in a certain place and this may be accompanied by the usual pain or an increase in local or general body temperature. Most often, infectious bumps change color at the site of inflammation and become red or burgundy. Headaches, malaise or weakness of the body may also begin. The most interesting thing is that such bumps, with proper treatment, can be cured in just a few days.

The most dangerous seals that appear under the skin are malignant tumors. They can be seen on their own or felt. They are actually no different from benign neoplasms, so if such a lump was found on the body, it is better to immediately contact a specialist to remove the seal.

Types of cones

Lipomas (wen)

Often, after people find bumps on their bodies, they immediately run to the doctors, and rightly so, but you should not worry right away, because seals can turn out to be just lipomas. These are a kind of fatty formations that belong to benign neoplasms and therefore cannot cause any harm to the body and human health.

Such fats are different having clear boundaries, no pain or discomfort. In addition, when a lipoma occurs, the color of the skin in the affected areas does not change. These bumps can appear on any part of the body, but are most commonly found on the neck, head, back, arms, and legs. Wen can be cut out with conventional surgery, but if they do not interfere, many people simply do not touch them.

Lipomas can only deliver discomfort in rare cases, when their growth does not stop and the wen simply begins to put pressure on organs or muscles, which leads to pain during movement.

Atheroma

A disease such as atheroma is often confused with ordinary wen among the people. Therefore, when atheroma occurs, people can simply forget about the appearance of bumps under the skin and do not go to the doctor, although in fact this disease is more serious and in some cases can even give complications to the body. Atheroma is not a wen, but a cyst. There is a whole list of differences by which you can distinguish atheroma from lipoma. First of all, it is worth checking the area of \u200b\u200bthe skin where atheroma develops into folds. If the skin does not gather into folds, then this is no longer a wen.

Atheroma is a tumor that is formed in case of blockage of the duct of the sebaceous glands. As a result, sebum begins to accumulate, which can lead to the formation of pus or simply become inflamed. It is impossible to cure atheroma with simple folk remedies, and the only way to remove it is surgical intervention.

Hygroma

On the wrists, it can often appear in the form of a hygroma bump. This neoplasm does not bring any harm to human health, except for spoiling the appearance, although most often such a ball under the skin is simply invisible. The hygroma can be removed surgically or disappear on its own in the event of a blow, but there will be no harmful consequences, since such a lump is just just a collection of fluid, which is located between the fibers of the tendons.

Nodules on the joints

Often on the joints with a disease, bumps or so-called small nodules can occur. Each disease has its own type of nodules on the joints. So, for example, if rheumatoid arthritis develops, then it is quite possible that rheumatoid nodule. Bumps, which are called Heberd's and Bouchard's nodules, may appear on the fingers in the event of the development of deforming osteoarthritis. Most often, such nodules develop to medium sizes.

Significant sizes can be gouty nodes or as they are also called tophi. Such bumps can appear in people who have been suffering from gout for several years, as a result of which the accumulation of salts begins.

It is also worth mentioning the subcutaneous bump, which is formed on the joints of the big toe. The growth of such a cone is accompanied hallux valgus, or rather, speaking, the finger simply begins to bend due to an increase in the bone. This, in turn, causes great discomfort while walking and when choosing shoes.

Hernia

One of the most famous formations under the skin is a hernia. Many people know what dangers the formation of a hernia can promise and why it occurs. Basically, a hernia can appear in the navel or under the skin in the groin. A hernia may be simple and not uncomfortable, but it can also be accompanied by pain symptoms.

No matter how strange it may sound, but often it is possible to set the hernia back with a simple finger pressure. More precisely, a hernia is formed with the help of internal organs, which, under pressure or heavy loads, simply squeezed out, so they can be safely adjusted, but it is better, of course, to contact a specialist. A hernia is usually caused by a load that puts too much pressure on the abdominal area. Also, a hernia can appear even during coughing or vomiting, because they contribute to an increase in local pressure.

Seals in the breast (in the mammary gland)

Seals in the mammary gland in women can be scary, but in fact, almost everyone has experienced this problem. Every woman has experienced the appearance of bumps or seals in the breast, and most often such a problem appears during menstruation. Small bumps or lumps may appear due to action of hormones on the mammary glands that just change over time. After the menstruation passes or just begins, such seals in the chest immediately subside.

There are possible cases when bumps remain even after menstruation, and this indicates that their occurrence lies in other reasons, so if the seals have not passed after menstruation, then it is best to contact a mammologist or gynecologist. Most often, these tumors are benign, and therefore they can be easily removed with conservative treatment or by surgery.

Reasons for urgent consultation with a doctor:

the node is rapidly increasing in size;
pain in the chest area appears regardless of the stage of the cycle;
the neoplasm does not have even contours and clear boundaries;
ulcers or skin deformity appear;
enlarged lymph nodes in the armpits.

If such symptoms appear after menstruation has ended, then it is best to immediately contact a mammologist or oncologist.

Malignant tumors

Unlike other skin lesions, malignant tumors very dangerous but they are extremely rare. Usually, the growth of this type of bump is no different from the appearance of any other seal. There are no pain or itching symptoms when a malignant tumor occurs, but it can be identified by several signs.

Symptoms and visual signs malignant tumor:

near the location of the lymph nodes increase in size;
rapid growth seal;
lack of clear boundaries;
practically does not move during probing;
the appearance of bruises or ulcers on the surface of the skin.

Malignant tumors can develop on the neck, back, arms, legs, that is, on any part of the body. Usually bumps appear on the sites of moles, and they can be located in the form of a sarcoma under the skin or in the area of \u200b\u200blymph nodes in the form of lymphoma. If there is a suspicion of the formation of a malignant tumor, then you need to urgently contact an oncologist.

Conclusion

As you can see, bumps, tumors, seals can appear anywhere on the body. The arms, legs, back, groin and neck are not protected from the appearance of a benign or malignant tumor, so at the first sign of appearance, you should consult a doctor who deals with such problems. This may be a dermatologist, a surgeon, or, in extreme cases, an oncologist if a malignant tumor is suspected. In any case, checking neoplasms is a chance to prevent the spread of a serious illness and protect your health.

The appearance of subcutaneous bumps on the human body can be due to several reasons: hematomas during injury, changes in the connective tissue, blockage of the skin glands. Malignant tumors are the most dangerous. Benign tumors are similar in appearance, but with careful examination at home, they can be identified. Treatment of such cones is done by removing them.

Lump under the skin - what is it?

Subcutaneous bumps can be several types of formations:

Benign tumors:
- atheroma;
- hygroma;
- lipoma;
- fibroxanthoma;
- hematoma;
- cyst.
Malignant (cancerous) tumors:
- lymphoma;
- metastases of cancerous tumors of internal organs.

The formation of dark red bumps with a blue tint on the inflamed area of the skin indicates the appearance of a boil. Most benign tumors are harmless to humans and are removed surgically. In any case, if formations appear under the skin, it is necessary to consult a dermatologist for an accurate diagnosis and to exclude a malignant process.

Dermatofibroma

Dermatofibroma (fibroxanthoma) most often appears in adults on the arms, legs and body. The most typical localizations are the following places:

shins;
soles of the feet;
forearm;
torso;
head;
palms of hands.

Dermatofibroma

Outwardly, this intradermal benign node looks like a button, has a dense texture, and when pressed, it hurts. The size of the cone is 0.3-1 cm in diameter. In color, it merges with the surrounding tissues, but is clearly palpable. Sometimes the skin over the ball is pigmented (due to constant trauma) or has a brownish color. The form of education is of two types - in the form of a tubercle or depressed. The surface is shiny or covered with scales. Scabs form when scratched or shaved.

A characteristic feature of dermatofibroma is its sinking when squeezed between two fingers, as the bump goes deeper under the skin. Usually, bumps appear in small numbers, but some people have several dozen of them, arranged randomly in different localizations. Degeneration into a cancerous tumor does not occur, the bump is only a cosmetic defect.

Dermatofibroma appears as a result of the growth of connective tissue. The reasons for its formation are unknown. It grows slowly, over several years, and can remain unchanged for many years. In some cases, the formations resolve themselves. If the tumor is permanently injured or is a serious cosmetic defect, then it is removed either surgically or with liquid nitrogen. It should be noted that after excision with a scalpel, a scar remains.

Hygroma

If a lump has formed in the joint area, then the presence of a hygroma, a cyst with liquid contents, can be suspected. Most often, hygroma appears in the following places:

wrist joint on the arm;
shins;
phalanges of fingers;
feet of legs.

Hygroma

Bumps can form in the area of any joints, including the sternocostal joint. Risk factors include the following:

monotonous load on the joint;
hereditary predisposition;
superficial location of the tendon sheath;
recurring injuries;
incomplete removal of the hygroma shell during the previous operation;
inflammatory diseases of the joints.

Hygroma can be identified by the following signs:

characteristic location near the tendons;
increase after exercise;
mobility relative to surrounding tissues;
slow growth;
unchanged color;
in some cases - peeling and redness of the surface of the bump;
in the area of a large tumor - numbness and tingling;
in advanced cases - soreness.

An accurate diagnosis of this benign formation is carried out using ultrasound. Hygroma is not dangerous, but it causes discomfort and leads to limited mobility. The bumps should be removed surgically (this is done with local anesthesia), since the contents of the cyst, when damaged, pour into the surrounding tissues and cause inflammation. If a secondary bacterial infection joins, then suppuration begins. Self-removal of the hygroma by squeezing it out is ineffective, since a capsule remains under the skin, which eventually fills with liquid again. It is also possible to divide the capsule with the formation of many daughter hygromas. With a decrease in physical activity, a temporary decrease or complete disappearance of the hygroma occurs.

Lipoma

Lipoma (wen, lipoblastoma) is a benign tumor of the subcutaneous fatty tissue layer. The formation of wen is due to several predisposing factors:

genetic heredity (familial lipomatosis);
liver disease;
endocrine diseases (diabetes mellitus, malfunction of the thyroid gland, pituitary gland, and others);
obesity;
polyps in the intestine;
helminthic invasions;
impaired kidney function, leading to the accumulation of toxins in the body;
frequent injury to the skin area;
constant mechanical friction.

Lipoma

Most often, lipomas form there, there is a fatty layer:

back of the neck;
stomach;
hips;
area under the jaw;
clavicle (often with pulmonary tuberculosis);
hands;
legs;
back;
axillary region;
breast;
face;
buttocks.

In more rare cases, a wen appears on the palms. Lipomas can also form in the tissues of the knee joint against the background of chronic inflammatory processes. The characteristic features of a lipoma are:

soft texture;
unchanged skin color;
round form;
when probing, you can feel the lobules;
absence of inflammatory processes;
good mobility relative to surrounding tissues.

Usually the size of the lipoma does not exceed 2-3 cm, but in rare cases it reaches a significant size. When it grows into muscle tissue, it becomes painful and inactive. Soreness also appears if the wen is massive and compresses the nerve endings. In most people, wen appear under the skin as single formations, but there are two hereditary forms of multiple rashes:

Madelung's syndrome, in which lipomas are located in large numbers symmetrically and can merge with each other. The disease is more common in men. Already in adolescence, many small wen appear (up to several hundred), which slowly grow over several years.
Derkum's disease (or morbid obesity) is the formation of many painful lipomas on the limbs and other parts of the body in girls and middle-aged women.

Multiple lipomas

Removal of wen is performed surgically, self-extrusion is not recommended, since the capsule remaining under the skin leads to the fact that the process of lipoma formation resumes. Under the influence of injuries, a lipoma can degenerate into a malignant tumor.

Atheroma

Atheromas are cysts of the sebaceous gland and are of two types that do not look different from each other:

congenital nature with improper embryonic development;
acquired, appearing as a result of blockage of the excretory duct of the sebaceous gland. Such atheromas can be a complication of acne.

Congenital atheromas are numerous. The localization of the cones is as follows:

acquired - on the scalp, on the shoulder, back and face;
congenital - on the face, neck and scrotum.

External signs of atheromas:

round form;
size 0.5-4 cm or more;
elastic consistency;
painlessness;
slow increase;
color - flesh or yellowish;
when squeezed, a thick mass of milky color with an unpleasant odor is released from the cone;
palpation mobility.

Lipomas are very similar to atheromas. External differences are as follows:

lipomas are soft to the touch, atheromas are harder;
the skin over the lipoma can be easily folded;
in atheroma, the skin is “soldered” with formation;
lipomas do not suppurate.

Inside the atheroma are sebum, decay products of sebaceous cells and keratin protein. If the atheroma becomes infected, then it suppurates, it becomes painful and spontaneously opens. In rare cases, malignant transformation occurs. Elimination of atheroma is performed only surgically, while it is important to remove the entire capsule of the formation so that there is no recurrence.

Hematoma

Hematoma is one of the most common forms of formation of seals under the skin. The "ordinary" bump that occurs upon impact is a hematoma. The signs of this subcutaneous formation are the following:

swelling at the site of formation;
soreness;
seal;
color - from bright red to purple, the color is heterogeneous.

A hematoma is formed from the fact that blood vessels burst under the skin. Blood flows into the subcutaneous tissue, and the skin itself remains intact. Traumatization occurs as a result of bruising, squeezing, pinching, impact. The size of the bump depends on how many vessels are affected.

The bump appears within 12-24 hours after the injury. Small hematomas resolve on their own. Large hematomas require surgical treatment. "First aid" for a hematoma is a cold compress (ice, a bottle of cold water, and others). Cold stops internal subcutaneous bleeding and helps reduce swelling. In case of extensive hematomas, it is necessary to consult a doctor.

Skin cyst

A cyst is an intradermal or subcutaneous cavity, the walls of which are lined with epithelial cells. Its content depends on the localization of education:

face (on the forehead, cheekbones);
torso;
hands;
scalp area;
oral cavity;
breast;
upper back;
scrotum and other parts of the body.

Cysts appear as a result of blockage of the skin glands (sweat, sebaceous, hair follicle), trauma, or are congenital. The external signs of this formation are as follows:

size 0.5-5 cm;
round form;
elasticity to the touch;
skin over the bump of the same color as in other areas;
thin wall;
clear borders of the cone;
hair loss in the area of a large cyst;
absence of pain.

When a bacterial infection is attached, redness occurs, signaling the onset of the inflammatory process. The contents of the cyst in the subcutaneous layer lead to inflammation, the cyst enlarges and becomes very painful. The appearance of a cyst at the base of the nail leads to its death. Therefore, it is necessary to remove it surgically by excision and drainage of the contents of the cavity.

Lymphoma

The manifestation of lymphoma - a malignant disease of the lymphatic tissue - begins with skin rashes of various forms that resemble dermatitis, eczema, psoriasis, lichen planus and other dermatological diseases. These rashes can exist on the skin for years and disappear for a while. At the last, third stage of the disease, tumors appear in the form of bumps that evolve at the site of other types of rashes or appear on healthy areas of the skin. The last symptom is a sign of metastasis. Bumps most often appear on the following areas of the body:

on the face;
on the neck;
on the elbow;
in the inguinal folds.

The bumps can dissolve on their own, but this does not mean the end of the malignant process in humans. The symptoms of lymphoma are as follows.

Hygroma

If a lump has formed in the joint area, then the presence of a hygroma, a cyst with liquid contents, can be suspected. Most often, hygroma appears in the following places:

wrist joint on the arm;
shins;
phalanges of fingers;
feet of legs.

Hygroma

Bumps can form in the area of any joints, including the sternocostal joint. Risk factors include the following:

monotonous load on the joint;
hereditary predisposition;
superficial location of the tendon sheath;
recurring injuries;
incomplete removal of the hygroma shell during the previous operation;
inflammatory diseases of the joints.

Hygroma can be identified by the following signs:

characteristic location near the tendons;
increase after exercise;
mobility relative to surrounding tissues;
slow growth;
unchanged color;
in some cases - peeling and redness of the surface of the bump;
in the area of a large tumor - numbness and tingling;
in advanced cases - soreness.

on the face;
on the neck;
on the elbow;
in the inguinal folds.

The bumps can dissolve on their own, but this does not mean the end of the malignant process in humans. The symptoms of lymphoma are as follows.
