Abstract

One hundred patients with facial seborrheic dermatitis and 42 control subjects were studied. The number of periodic acid-Schiff-positive Pityosporum ovale yeast cells in skin scrapings per high-power field were counted and designated 1 + to 4+. Our data indicate a correlation between the density of P. ovale and the clinical severity of seborrheic dermatitis, both before and after therapy with a precipitated sulfur/salicylic acid shampoo. The data support the concept that yeast contributes to the pathogenesis of seborrheic dermatitis.
