Pityriasis versicolour is a non-inflammatory superficial fungal infection of the skin that occurs mainly in young people and adolescents of both sexes.
Pityriasis versicolour causes spots of different colors (depending on the phototype of each), which have a light scale and are located on the back and upper part of the chest and arms. During the scraping of the plates, dandruff and slightly greasy scales fall.
Pityriasis versicolour is a persistent form of fungal infection and should be diagnosed by a dermatologist. The treatment is done with topical antifungals . Your doctor may also recommend a shampoo with ketoconazole or selenium sulfide for daily shampooing, as the fungus settles on the scalp.
If the patient does not receive treatment, the fungus develops over years. But even if cured, it often relapses due to insufficient treatment time or predisposition.
