Objective: Pityriasis amiantacea (PA) is characterized by thick, silvery, adherent scales, which surround the base of scalp hair. The exact cause of PA is unclear and it is claimed to be a reaction pattern of the scalp to various inflammatory scalp conditions. In this study, we intended to describe the clinical features, to search the microbiologic etiology and to evaluate the associated diseases. Methods: Archive files of 47 patients, who had attended to our clinic between January 2009 and April 2010 and diagnosed with PA, were evaluated. Clinical properties, bacteriologic and mycological laboratoary results of all patients and histopathological diagnosis of 36 patients were recorded in the database.
