Atypical antipsychotics and seborrheic dermatitis: three case reports.

Seborrheic dermatitis (SD) has no diagnostic criteria and its etiology remains unknown. SD is distributed in the areas rich in sebaceous glands. Initially, MALASSEZIA FURFUR was thought to be the causing agent. Currently, SD is thought as not being proportional to the mean yeast count, but rather as an abnormal host immune response to the yeasts on the skin. There are a variety of topical and systemic antifungal agents available as a remedy. Corticosteroids and ultraviolet B are also used as treatment.
