A Case of Steatocystoma Simplex Involving the Scalp

Posted by James

INTRODUCTION

Steatocystoma simplex, first described as a dis­tinct entity by Brownstein in 1982, is an extremely rare benign adnexal tumor. The individual lesion of steatocystoma simplex is usually identical with that of steatocystoma multiplex, both clinically and histologically, but is characterized by solitary, non- heritable growth in adulthood. Steatocystoma sim­plex occurs predominantly on the face, but the incidence of steatocystoma simplex on the scalp is extremely low. Only three cases of steatocystoma simplex on the scalp have been reported world­wide. We report an additional case of steato- cystoma simplex which was developed on the right parietal scalp.
