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.
皮脂腺囊肿是一种起源于毛囊皮脂腺导管交界处的良性附属器肿瘤。它可分为两组（单纯性皮脂腺囊肿和多发性皮脂腺囊肿）。单纯性皮脂腺囊肿表现为成人中孤立的、非遗传性的非常罕见的病变。它最常见于腋窝、胸骨区和手臂。头皮是极其罕见的发病部位。我们报告一例49岁男性，于2017年2月入住孟加拉国达卡达卡医学院医院外科，其左顶叶头皮有一个缓慢进展的无痛、柔软、淡黄色、表面光滑的单个肿块，已持续8年。组织病理学检查显示一个薄壁囊肿，由缺乏颗粒层的复层鳞状上皮组成，壁附近有皮脂腺。这些发现符合皮脂腺囊肿。在4个月的随访中，没有皮脂腺囊肿或任何其他肿块复发或进展的迹象。
