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). All patients attended our department were evaluated clinically and underwent bacteriologic, mycologic and histopathologic examinations. 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. Pathological diagnosis of scalp psoriasis was confirmed in 35.3% of | cases. Eczematous features suggesting a diagnosis of seborrheic and atopic dermatitis were detected in 34.2%. I Diagnosis of tinea capitis proved by KOH preparation, fungal culture and periodic acid Schiff staining, was detected in 12.9% of
