Eruptive steatocystoma multiplex on the scalp.

We report a 71-year-old Japanese woman who noticed approximately 120 small yellowish cysts on the scalp from nine months before her first visit. An incision made into the cysts discharged oily yellow material. Biopsy of a lesion disclosed that the cysts had typical features of steatocystoma multiplex histologically. This case was a unique eruptive variety of steatocystoma multiplex on the scalp.
