Abstract Pityriasis amiantacea (PA) is a clinical syndrome that affects the scalp and characterized by thick, silvery adherent scales which surround and bind down tufts of hair. The studies of series of pityriasis amiantacea in English-language medical literature are limited and mostly retrospective. We prospectively analyzed the clinical and aetiopathological factors in a large series of PA diagnosed at our department within a defined period (2000-2001).

Forty healthy control persons were subjected to bacteriologic and mycologic investigations of their scalp hairs. A total of 85 PA patients were collected and studied.

I Diagnosis of tinea capitis proved by KOH preparation, fungal culture and periodic acid Schiff staining, was detected in 12.9% of |
