  • Oval( ovale);
  • Round( orbiculare);
  • Mycelial( Malassezia furfur).

The first two forms of Pityrosporum are representatives of normal skin microflora and do not represent any danger.And Malassezia furfur is a pathogenic form of the fungus, which leads to the development of pityriasis.Forms of Pityrosporum can pass into each other.

Transformations of nonpathogenic forms of the fungus into the mycelial are facilitated by certain factors:

  1. Increased sweating of the skin;
  2. Pityriasis Change in sweat composition;
  3. High temperature and humidity of the environment;
  4. Diseases of the digestive tract;
  5. Infectious diseases;

Fungus affects the stratum corneum, which causes skin peeling.In most cases, pityriasis is not accompanied by any uncomfortable sensations, only occasionally there is a mild itching.

Pityriasis is a long-lasting disease that can last for months and years.After the recovery, recurrences of the disease are not excluded.

Diagnostics

Leukocytes The clinical picture of pityriasis is so characteristic that it is not difficult to determine the correct diagnosis for a doctor.To confirm the diagnosis, an iodine test is performed.Skin areas along with stains are treated with a 5% iodine solution.The area of ​​the skin, where the horny layer of the skin is very loose - stains more than the healthy skin.Confirm the discernible lichen allows the phenomenon of "shavings" when when patching the spots the upper layers of the skin slough.

For the detection of hidden foci of lichen, a mercury quartz lamp is used.The study is conducted in a dark room.When the skin is illuminated by a lamp, the staining spots are fluoresced with a reddish-yellow or brown light.

In addition, to confirm the diagnosis, scraping of the skin and its microscopic examination are performed.Under the microscope, it is possible to detect the elements of the fungus, the mycelium.

Treatment of pungent lichen

Treatment of pityriasis is based on the use of antifungal agents.In most cases, these drugs are used externally in the form of creams and ointments and only rarely inward in the form of tablets.

These groups of antifungal agents are used:

  • Imidazole derivatives - ketoconazole, miconazole, clotrimazole;
  • Allylamine compounds - lamizil, terbinafine;
  • Pyroxolamine derivatives are cyclopyrox, tolcyclate.

Ointments are applied once or twice a day, and the course of treatment on average lasts two to three weeks.

-orngal-treatment-fungus In the absence of the desired result from local therapy and in severe forms of the disease, antifungal drugs( introconazole, orungal, fluconazole) are prescribed as tablets orally.

At the end of the use of antifungal agents, treatment of the foci with salicylic alcohol is shown for two weeks.This substance contributes to the rejection of the horny layer of the skin.

Given that pityriasis often affects the scalp, it is necessary to use antifungal shampoos, for example, Nizoral.By the way, such shampoos when deprived can also be used as a shower gel.

Prevention

Smoothing-things Pityriasis lichen is infectious.And nevertheless, the patient should use strictly individual clothes, bed linen, towels.The rest of the family should see a dermatologist in order to identify a possible pityriasis lichen from them.

During the treatment it is necessary to constantly disinfect bed and underwear, towels, clothes by boiling in a one-percent soap-soda solution, followed by a five-fold smoothing of wet things with a hot iron.

The fungus feels particularly comfortable in the warm season.Therefore, in order to prevent relapse, prophylaxis should be carried out from March to May.For this purpose, shampoos with ketoconazole( for example, Nizoral) are used to treat the scalp and body every month for three consecutive days.In addition, you can treat the skin with salicylic alcohol once a week.

People with pityriasis in the history should be carefully monitored with hygiene, regular water procedures, and avoid excessive sweating.
