Lichen versicolor according to ICD 10. Lichen versicolor - description, causes, diagnosis, treatment

Pityriasis versicolor is a fairly common disease. Spots of various shades appear on the skin.

Refers to fungal diseases. How to get rid of this type of lichen?

About lichen

Pityriasis versicolor is a skin disease caused by yeast-like fungi. This fungus is detected in 90% of people in the upper body and scalp. It can stay there for a long time, but not show itself in any way.

Pityriasis dermatosis gets its name from the fact that it causes the skin to peel off quite a lot. This type of lichen is also called multi-colored due to the fact that the spots can be of different shades. Most often, the disease is diagnosed in the summer season, for which it is popularly called “sun fungus.”

Pityriasis disease affects young and middle-aged people; in children and the elderly, lichen is quite rare.

Pityriasis versicolor in humans has a code according to ICD 10 - B 36.0. ICD 10 describes the causes, diagnosis and treatment of pityriasis versicolor.

The disease affects the upper part of the body without spreading to the lower part.

Causes and symptoms of lichen

Why might a person develop pityriasis versicolor? The exact cause of the appearance has not yet been established.

Experts identify certain factors that can trigger the development of the disease. Their influence causes the transition of the fungus from a saprophytic to a pathogenic form, which leads to its spread.

Factors:

• Weak immune system
• Chronic depression, nervous shock,
• Diseases of the endocrine system (diabetes mellitus),
• Lack of control when taking medications with hormones, antibiotics,
• Changes in the chemical composition of sweat,
• Prolonged and frequent exposure to sunlight, excessive use of solariums,
• Increased sweating
• Diseases of the gastrointestinal tract, liver, kidneys,
• Diseases of the respiratory system,
• Synthetic clothing.

The main reason is considered to be weak immunity. Pityriasis dermatosis is often diagnosed in people with immunodeficiency virus and cancer.

In adolescents, lichen often appears due to hormonal changes in the body and changes in the functioning of the sebaceous glands.

Lichen is often diagnosed in pregnant women and women during menopause. This is due to hormonal changes in the body.

Is tinea versicolor contagious? The disease can be transmitted from one person to another. In normal health, in the absence of unfavorable factors, the disease does not develop. The disease progresses with weakened immunity. The incubation period for lichen is one and a half months.

Clinical picture

How does pityriasis versicolor manifest? What symptoms should you look out for?

Symptoms:

• Pityriasis dermatosis spreads over the upper part of the body, involving the chest, neck, upper and lower limbs, and head. Less commonly, the rash is observed in the groin area and inner thighs.
• At the first stage, the appearance of points of yellow light in the mouth of the hair is noted.
• They gradually increase to one centimeter.
• The spots gradually become pink, then change shade to brown.
• The disease damages only the upper layer of the dermis, without penetrating into the depths.
• Gradually, the plaques begin to peel off and scales form.
• Sometimes several spots can merge into one with uneven boundaries. There is no symmetry.
• When exposed to the sun, skin damaged by the disease does not tan and remains white.
• The person has no pain or itching.

Pityriasis dermatosis is characterized by a long course with periodic exacerbations.

Pityriasis versicolor on the head and face

Pityriasis dermatosis on the head appears in the form of flaky spots with a yellow or brownish tint. The affected areas begin to become bald intensively. Most often, lichen occurs on the back of the head.

When wounds occur on the face, the patient experiences discomfort and itching. Quite often there is a merging of spots into one whole.

The most common causes of pityriasis dermatitis on these parts of the body are prolonged exposure to the sun and excessive sweating. Therefore, the disease is diagnosed mainly in the warm season.

Ringworm in children and pregnancy

In children, lichen of this type is diagnosed quite rarely. It occurs as a result of a weakened immune system, constant stress and increased sweating.

Experts note the frequent occurrence of the disease in children due to the use of various antibacterial bathing agents. In most cases, children over 10 years old are susceptible to pityriasis dermatitis.

The disease in children has similar symptoms as in adults. The incubation period is approximately three weeks.

Women during pregnancy are also susceptible to pityriasis dermatitis. At this time, immunity decreases, hormonal levels change, which provokes the activity of fungi.

This type of lichen does not have an adverse effect on the expectant mother and baby, but pityriasis versicolor dermatosis needs to be treated. Specialists will select the safest drugs for internal and external use.

Treatment of deprivation with medications

How to treat pityriasis dermatitis? Treatment of lichen does not cause any particular difficulties. However, you should not engage in self-therapy. If signs of the disease appear, you should consult a specialist.

Treatment of pityriasis versicolor involves the use of antifungal agents for internal and external use.

What is the most effective ointment for pityriasis versicolor?

External means:

1. Medicines based on terbinafine. These agents have a detrimental effect on fungal cell membranes. They are not allowed to reproduce. The use of such ointments helps to avoid the spread of infection. The representative is the drug Terbinafine. It can be found on sale in the form of a spray or cream. Apply to the skin according to the instructions twice a day. The substance terbinafine also contains Binafin, Lamisil, Mycoterbin, Exifin.
2. Effective treatment is carried out using drugs containing imidazole. Such drugs have a detrimental effect on fungal cells, quickly destroying their membrane. This group includes Clotrimazole, Miconazole, Ketoconazole. They are sold on sale in the form of ointments. Apply to damaged areas twice a day. For hair therapy with ketoconazole in the composition.
3. Products based on pyroxolamine. The use of these products leads to the death of fungi as a result of the lack of substances necessary for them. This group includes Tolcyclate, Ciclopirox. Ointments are applied to the lesions up to two times a day.

It is worth noting Triderm cream. The drug contains clotrimazole, betamethasone and gentamicin. In addition to antifungal properties, it is an antibacterial agent. Acts quickly, use morning and evening, rubbing into damaged areas. from other types of lichen.

If it is impossible to use antimycotic agents, plaques can be treated with iodine solution or sulfur-salicylic ointment.

In case of severe pityriasis dermatitis, the doctor may prescribe medications for internal use. Fluconazole and Intraconazole tablets have antifungal properties. The dosage is prescribed by the attending medical professional, based on the patient’s condition.

All treatment is carried out at home and does not require a hospital stay. The drugs are used according to the indicated dosages to avoid side effects. We should not forget about contraindications.

Treatment at home can also be carried out using folk remedies.

Methods:

• Finely chopped sorrel is mixed with sour cream 1/1. Compresses are made from the resulting mixture for stains.
• You can lubricate the plaques with St. John's wort ointment. The plant powder is mixed with petroleum jelly and used as is. St. John's wort oil helps a lot.
• Wipe stains with apple cider vinegar up to six times a day.
• The fragrant rue herb is crushed and mixed with butter in a ratio of 1/5. The resulting product lubricates the damage.
• You can wipe the spots with calendula juice or tincture.
• Finely chop the onion and squeeze. The resulting juice is used to treat fungal infections.

Treatment with folk remedies for pityriasis versicolor should be accompanied by accuracy and caution. If allergic reactions, inflammation, or irritation occur, therapy should be stopped.

Prevention and reviews

To avoid the onset of illness, it is necessary to monitor the state of the immune system, treat all diseases in a timely manner, and try to avoid nervous stress and shock. Frequent exposure to fresh air, moderate physical activity, proper nutrition, and control of medications have a beneficial effect on the body's condition.

Pityriasis versicolor is an unpleasant disease that causes a certain amount of discomfort to a person. It can last for quite a long time, appearing periodically. Therapy is selected based on the patient’s condition and the advanced stage of the disease.

Versicolor versicolor (synonym: pityriasis versicolor) (Pytiriasls versicolor) is a low-contagious chronic disease of predominantly young and middle-aged people, characterized by damage to the stratum corneum of the epidermis and a very mild inflammatory reaction and caused by the lipophilic yeast-like fungus Pityrosporum cibiculare.

ICD-10 code

B36.0 Tinea versicolor

Causes of pityriasis versicolor

The causative agent of the disease is Mallasseria furfur. Lichen versicolor occurs as a result of transformation of the saprophilic form into a pathogenic one or infection from the outside. The development of lichen versicolor is facilitated by a weakened immune system, increased sweating, and endocrine disorders. The occurrence of the disease is facilitated by changes in the physicochemical properties of the water-lipid mantle of the skin and the keratin of the stratum corneum. They can be caused by increased sweating, seborrhea, as well as some endocrine disorders (Cushing's syndrome, diabetes mellitus, obesity, hyperthyroidism, etc.). The disease occurs in all geographical zones, but more often in regions with hot climates and high humidity.

It has been established that the pathogen's lipoxygenase oxidizes unsaturated fatty acids in sebum into dicarboxylic acids. As a result, melanocyte tyrosinase is inhibited and melanin synthesis in the lesion is reduced. The disease often occurs in HIV-infected patients.

Symptoms of versicolor

Both men and women suffer from tinea versicolor.

The rashes are often localized on the chest, back, and armpits; from here the rash spreads to the shoulders, sides of the torso, and abdomen. The disease pityriasis versicolor begins with the appearance of pinkish, scaly spots that quickly turn brown.

As a result of peripheral growth, the initial elements turn into round, sharply defined spots up to 1 cm in diameter. The spots can merge and form large lesions that occupy the entire back, torso and chest. The elements have scalloped outlines, with isolated spots scattered around their periphery. The color of the rash varies widely from pale cream to dark brown. The surface of the rash is covered with pityriasis-like scales, formed as a result of the fungus loosening the stratum corneum of the epidermis. With frequent washing, the scales are hardly noticeable, but when scraped, mealy peeling easily occurs (Beignet's symptom). There are forms similar to erythrasma, urticaria, reminiscent of vitiligo. Subjective sensations are usually absent.

After artificial ultraviolet irradiation, white pseudochromic spots remain in the area of ​​the rash. The course of the disease is long and can last for many years.

Diagnosis of lichen versicolor

The diagnosis of “lichen versicolor” is established on the basis of a characteristic clinical picture and laboratory data. To confirm the diagnosis, the Balzer test is used: lesions and adjacent areas of healthy skin are smeared with 5% iodine tincture (at a lower concentration the test may be dubious) - rashes due to loosened The stratum corneum is colored more intensely than the surrounding healthy skin. During fluorescent examination using a Wood's lamp, a yellow glow is observed in the lesions. In the rays of a fluorescent lamp, the lesions glow golden yellow. The morphology of the pathogen upon microscopic examination of scales from lesions is very characteristic (short, wide, curved pseudomycelium and single or large spores arranged in clusters).

Pityriasis versicolor (synonym: pityriasis versicolor) is a fungal infection of the superficial stratum corneum of the skin (epidermis) in humans.
Latin name: Pityriasis versicolor
ICD10 code: B36.0
Other synonyms: yellow lichen, multicolored lichen, sun fungus, sun or beach lichen.

Treatment for pityriasis versicolor is with a dermatologist.

Causes

The only cause of pityriasis versicolor in humans is the yeast-like fungus Pityrosporum (that is, it is similar to yeast fungi).
This pathogen has three forms: Malassezia furfur (mycelial form), Pityrosporum orbiculare (round form) and Pityrosporum ovale (oval form of the fungus). Normally, a person may have Pityrosporum orbiculare and Pityrosporum ovale in their skin, but they do not cause lichen. Once these forms of the fungus transform into the Malassezia furfur form, the person develops tinea versicolor.

Mostly young people, often men, are affected in countries with hot and humid climates. Children and old people rarely get sick.
If pityriasis versicolor appears in a child or an elderly person, you should look for the underlying disease or predisposing factor that led to the development of a fungal infection on the skin.

The disease is chronic and relapses occur frequently.

Contagiousness (that is, infectiousness) is low. That is, the fungus, of course, is transmitted from person to person. But you are unlikely to be able to become infected with pityriasis versicolor from a patient. After all, with a 90% probability, every person on Earth has this pathogen.

In addition to the main cause, there are predisposing factors that contribute to the development of fungus in human skin:

• diabetes mellitus and other endocrine diseases,
• HIV and immunodeficiency as a result of treatment for blood cancer,
• increased sweating of the human body,
• stress,
• hereditary predisposition, special composition of sweat and excess sebum,
• diseases of the gastrointestinal tract,
• in general - a decrease in immunity, which is designed to fight the fungus.

Symptoms

On the head

If pityriasis versicolor is located on the scalp, it is called seborrhea, or dandruff.

The symptoms are exactly the same - spots, itchy scalp, flaking. At the same time, it is peeling that most often worries patients.
How to treat pityriasis versicolor on the head and other hairy areas of the body - and in the same way as on other parts of the body. Just choose not a cream or ointment, but a spray or solution for external skin treatment plus shampoo with an antifungal agent.

Diagnostics

The diagnosis of pityriasis versicolor in a person is made on the basis of:

1) Main symptoms: spots on the skin of different colors, merging into conglomerates.

2) Pityriasis-like peeling of spots.

3) Spots without inflammation.

4) Diagnostics under a microscope is the main instrumental method for diagnosing lichen versicolor. Scrape off exfoliated skin particles from the surface of the spots, treat with potassium alkali and look under a microscope. Both the mushrooms themselves and their mycelium are visible.

5) Examination of the skin under a Wood's lamp. Wood's lamp is an ultraviolet fluorescent lamp with a magnifying glass for examining the skin.
Pityriasis versicolor spots under a Wood's lamp give a yellow-greenish or reddish-brown glow different from the surrounding skin. Moreover, lichen spots of different colors also give a different glow under a Wood’s lamp.

What does pityriasis versicolor look like under a Wood's lamp?

6) Iodine test, or Balzer test, is an important diagnostic symptom. It can be done at home and if not diagnosed, then suspect the diagnosis of versicolor versicolor yourself.
Take iodine tincture, lubricate the spots and surrounding healthy skin. After a few seconds, wipe so that there are no drops of iodine on the skin. Healthy skin becomes yellowish, and pityriasis versicolor spots overabsorb iodine and turn brown.

7) Beignet's sign, or floury peeling. When skin lesions are scraped, for example with a glass slide or scalpel, fine flour-like peeling appears.

Beignet's sign - floury peeling

Differential diagnosis is carried out:

• With Becker's nevus in the stage when there is no hair growth yet.
• Zhiber's rosacea is also in the initial stage.

Treatment

Treatment of pityriasis versicolor has only cosmetic indications, since there is no inflammation or damage to other organs in this disease. Such patients are not contagious, since the fungus is present in almost all people, it’s just a matter of immunity.

How to treat pityriasis versicolor:

1) Correction of the underlying disease (if any) that led to the appearance of pityriasis versicolor. We must not forget about this direction. It is imperative to get rid of the provoking factor.

2) Local skin treatment.

Always done.
Creams, ointments, shampoos, sprays and solutions with antifungal (antimycotic) agents are used.

Exactly the same treatment regimen when using the following local antifungal agents:

• clotrimazole (cream or solution),
• miconazole (cream),
• terbinafine (Lamisil) – cream,
• fungoterbin (spray or gel),
• oxiconazole (cream),
• termikon (spray or cream).

If lichen versicolor affects areas with hair growth (on the head, groin, labia or penis), it is better to use sprays or solutions of the above-mentioned drugs rather than ointments or creams.

3) General treatment.

Mandatory:

• for widespread lesions over large areas of skin,
• with weakened immunity,
• if local treatment is ineffective after 2 weeks.

But a number of dermatologists advise always using systemic antifungal drugs simultaneously with creams or ointments. The effectiveness of this treatment is higher due to its effect on fungi in the hair follicles.

Attention: general treatment without local treatment is ineffective!

Antifungal drugs are prescribed in tablets or capsules that must be taken orally.

• Fluconazole (150 mg capsules). How to take: 2 capsules 1 time per week for a course of 2 weeks. That is, we took 2 capsules on Monday, and a week later - 2 more capsules. Fast, cheap and effective.
• Itraconazole – 200 mg once a day – for 1 week.
• Ketoconazole - 200 mg once a day - for 3-4 weeks.

Approximate treatment plan for pityriasis versicolor

1. Fluconazole – 2 capsules 1 time per week – course 2 weeks.
2. Nizoral shampoo - wash your hair and body every evening for the first week. And every other day - 2 and 3 weeks.
3. Instead of Nizoral, you can use Thermikon spray for the body - apply once a day to the affected areas for 3 weeks.
4. Salicylic acid – lubricate the affected areas once a day in the morning.
5. Taking multivitamins (Complivit, Selmevit and others).
6. A set of activities to improve immunity.

Treatment of pityriasis versicolor during pregnancy

Peculiarities:

• You should not take any antifungal agents orally, as they may have a negative effect on the fetus.
• Externally, locally, it is best to use Nizoral shampoo. And only in cases where the benefit to the mother’s body outweighs the risk to the fetus. Treatment should be agreed with your gynecologist.
• In most cases, it is better to wait until childbirth and then carry out a full course of treatment.
• Remember: the pathogen has no effect on the fetus and does not affect childbirth.

When breastfeeding

• Do not take medications internally.
• Do not apply ointments or creams to your breasts.

How to evaluate the effectiveness of treatment?

1. The first symptom should disappear - peeling on the spots.
2. The spots should go away, at least the pink and brown ones. White spots may persist for some time until the skin evenly tans in the sun.
3. There should be no mushrooms or threads of fungal mycelium in the skin scrapings.

Prevention

Remember: just because the stains are gone, it doesn't mean they won't come back. The disease is chronic and cannot be cured forever. Therefore, prevention is mandatory!

• Taking ketoconazole - 400 mg once a month - every month. Or taking another antifungal drug.
• In the month of May, before the summer period begins: Nizoral shampoo - wash once a day - 3 days in a row.
• Wash clothes at 95% for the entire treatment period.
• Iron clothes with a hot iron for the entire treatment period.
• Do not wear synthetic clothing - it does not absorb sweat.
• In case of excessive sweating: use antiperspirants and change clothes frequently!
• Treatment of all diseases and correction of conditions that led to the appearance of pityriasis versicolor.
• Strengthening the immune system using different methods is a must!!!
• Is it possible to go to the solarium and sunbathe? During treatment - not allowed. After treatment, you can and even need to lightly sunbathe in the sun, since sunlight kills the pathogen - the fungus.

Pityriasis versicolor (lichen versicolor)- fungal skin disease.

Code according to the international classification of diseases ICD-10:

Causes

Diagnostics

Diagnosis based on characteristic clinical symptoms and a positive iodine test. In doubtful cases, a microscopic examination of skin flakes is performed to detect the pathogen. Differential diagnosis is carried out in some cases with syphilitic roseola, which does not peel off, does not merge into solid foci, the iodine test is negative, and serological reactions to syphilis are positive; there may be other manifestations of syphilis. Pseudo-leukoderma must be differentiated from true syphilitic leukoderma, in which small round (0.5 - 1 cm) or marbled hypopigmented spots without clear boundaries are located on the slightly pigmented skin of the back and non-lateral surfaces of the neck, sometimes spreading to the skin of the back; positive serological reactions and other signs of syphilis make it possible to distinguish it from pseudoleukoderma.

Treatment

Treatment. Rubbing in Andriasyan's liquid (urotropine - 5 g, 8% acetic acid solution - 35 ml, glycerin - 10 ml), 2 - 5% salicylic-resorcinol alcohol, Wilkinson ointment, 10% sulfuric ointment, mycozolon, treatment according to the Demyanovich method (see. Scabies) and other antifungal agents for 3 to 7 days, after which a general hygienic bath with soap and a washcloth is prescribed. To prevent relapse of the disease, it is advisable to treat the entire skin. For cosmetic purposes, ultraviolet irradiation is indicated to eliminate pseudoleukoderma after antifungal treatment.

Diagnosis code according to ICD-10. B36.0

Tinea versicolor (pityriasis versicolor, tinea versicolor) is a superficial fungal skin disease that belongs to the group of keratomycosis.

Etiology and epidemiology

The disease is widespread, but is most common in regions with hot and humid climates. Mostly young and middle-aged people are affected; children and the elderly are extremely rare.

The causative agents of pityriasis versicolor are dimorphic lipophilic yeasts of the genus Malassezia - representatives of typical skin microflora. The most frequently found are Malassezia globosa, M.sympodialis and M.furfur, and less frequently – M.slooffiae, M.restricta and M.obtusa. It has been established that about 90% of healthy people are carriers of the saprophytic form of the fungus. Under the influence of predisposing factors of an endogenous and/or exogenous nature, the pathogen is transformed from a non-pathogenic form of budding blastospore into a pathogenic mycelial one.

The contagiousness of the disease is low. Predisposing factors may include increased sweating, changes in the chemical composition of sweat, and a decrease in physiological peeling of the epidermis. Lichen versicolor often develops in people with concomitant diseases: endocrine pathology, chronic diseases of the lungs and gastrointestinal tract, vegetative-vascular disorders, immunodeficiencies of various natures, etc. Nutritional deficiency, taking oral contraceptives, systemic glucocorticosteroid drugs and immunosuppressants contribute to the development of the disease. There may be a genetic (multifactorial) predisposition to the development of the disease. Immune factors may be involved in the pathogenesis, but they are difficult to interpret. Patients with lichen versicolor do not have cell-mediated immunodeficiency to mycelial antigens of Malassezia spp.

Classification

Absent.

Clinical picture (symptoms) of pityriasis versicolor

The rashes are most often localized on the skin of the torso and upper extremities; the skin of the scalp and penis may be affected.
Atypical localizations of lichen versicolor include: face, ears, postauricular folds, hands, legs, inguinal and axillary regions, nipple and periareolar region. In children, the disease often begins on the scalp, but the hair is not affected. Tinea versicolor is not observed on the palms, soles and mucous membranes. The tropism of the pathogen towards areas of the skin with a large number of sebaceous glands is noted.

The disease is initially characterized by the appearance of small spots without inflammation, blurred, first pink, then yellowish-pink, later brown or red-brown; on their surface there is a fine-plate peeling, similar to bran (pityriasis versicolor), easily determined by scraping. The spots are often multiple and can merge to form large lesions with polycyclic outlines; the size of the spots varies from a few millimeters to several centimeters. Sometimes, when examining large lesions, mild atrophy can be determined in their center. As a result of central involution, the lesions can take on a ring-shaped form. There are usually no subjective sensations, but sometimes mild itching may occur. After tanning, as a result of increased peeling, depigmented areas of skin remain in the affected areas.

There is a special form of the disease - tinea versicolor alba, or pityriasis versicolor. In this case, complete depigmentation may occur in the absence of any peeling. Depigmentation in this case is not directly related to the shielding properties of fungal colonies and can occur in areas of the skin that have not been exposed to solar radiation.

Diagnosis of pityriasis versicolor

The diagnosis in most cases is established on the basis of a typical clinical picture: characteristic rashes on the skin of the trunk and upper extremities.
In case of erased forms and/or atypical localization, the diagnosis is established based on the results of examination in the rays of a Wood's fluorescent lamp based on the characteristic yellow or golden-brown glow. Glow in the rays of a Wood's lamp is observed mainly in cases where the etiological agent is M. furfur (about 1/3 of cases).

Microscopic examination of scales treated with a 10-20% solution of potassium hydroxide (KOH) with a 20-minute exposure reveals elements of the fungus (short curved filaments of mycelium (hyphae) from 2 to 4 microns in diameter and large round and oval spores with a double-circuit shell in in the form of clusters resembling bunches of grapes).

When making a diagnosis, the Balzer test (iodine test) can be used: when the areas are lubricated with 5% tincture of iodine, the spots of pityriasis versicolor become stained with iodine more intensely due to the impregnation of the pityriasis scales.

Balzer test

Histological examination of the affected areas of the skin using the PHIK reaction can detect mycelium and rounded spores of the fungus in the stratum corneum of the epidermis.

Differential diagnosis

The disease in the acute stage should be differentiated from Zhiber's pityriasis rosea, syphilitic roseola, seborrheic dermatitis, eczematids, erythrasma; with a long course - with pigmentation observed after the resolution of various dermatoses, Becker's nevus. In the presence of depigmented spots - with syphilitic leukoderma, dry streptoderma, vitiligo, depigmented eczematids.
