Abstract

Steatocystoma is a benign adnexal tumor arising from the pilosebaceous duct junction. It can be classified into two groups (steatocystoma simplex and steatocystoma multiplex). Steatocystoma simplex, which presents as a solitary, non-herited very rare lesion in adult. It occurs most commonly in the axillae, in the sternal region and on the arms. Scalp is an extremely rare location. We report a case of 49-years-old male admitted in Department of Surgery, Dhaka Medical College & Hospital, Dhaka, Bangladesh on February 2017 presented with slowly progressing painless, soft, yellowish, single smooth surface mass on the left parietal scalp which had persisted for a period of 8 years. The histopathologic examination revealed a thin-walled cyst consisting of stratified squamous epithelium with lack of granular layer and containing sebaceous gland close to the wall. These findings were consistent with steatocystoma. At the 4-month follow-up, there was no sign of recurrence or development of the steatocystoma or any other masses.
