What is pityrosporum folliculitis?

pityosporum folliculitis (PF) is one of the skin conditions caused by the yeast malassezia furfur and is also called folliculitis malassezia. It is characterized by inflammation and manifested as itching or itchy skin lesion on the upper trunk. Pityosporum folliculitis is diagnosed on the basis of the presence of increased, itchy lesions called papules and pustules and often affects young or medium adults. It is distributed on the hair follicles of the back and chest. The neck and upper arms can occasionally be involved, but the face is rarely affected. Patients who have pityosporum folliculitis often have coexisting seborrheic dermatitis. The case agent was initially classified as pityosporum yeast, namely pityosporum ovale and pityosporum orbiculare, but these species were later -classified into the family Malassezia. Malassezia species are considered superficial mycas because they do not generally be involved as a baked or keratinized layer of skin. Pityrosporum folliculitis is unique because it attacksDeeper and central parts of hair follicles.

The causal agent is lipophilic or loving oil, so it thrives in the environment of the hair follicle, where there are numerous sebaceous or oil glands. Fatty acids are released when pityosporum yeast becomes excessively and due to a favorable environment, resulting in the connection of the hair follicle. These events evoke an immune response mediated by the cell and activate the complement path. The final result is inflammation that manifests itself as itching, swelling of hair follicles, redness and pus formation.

In addition, pityosporum yeast is the most abundant on the back, chest, shoulders, scalp and upper weapons, which are areas where this condition is most common. When these areas are examined under an apparatus called a wooden lamp, they fluores or emit bright blue or white light. The affected areas can be scraped off to makeRock sample for microscopic examination. When the potassium hydroxide (KOH) is added to this sample, yeasts can be visualized. Other testing, such as culture or skin biopsy, is rarely performed.

local and oral antifungals are used to treat pityosporum folliculitis. Oral drugs are considered more effective because lesions can be cleaned immediately after reception. Some oral antifungals used for this skin disorder are ketoconazole, itraconazole and fluconazole. Shampoos with local ketoconazole can be added to make treatment more efficient.
