Steatocystoma multiplex (SM) is an uncommon disorder of the pilosebaceous unit characterized by the development of numerous sebum-containing dermal cysts which rarely involves the scalp. Here, we report a case of a 50-year-old man with multiple cystic nodules and alopecic patches on his scalp. On histopathological examination, the folded cyst was found to be lined by stratified squamous epithelium, while flattened sebaceous gland cells were identified in the cystic wall. Pigment casts were present in the hair papillae and perifollicular regions, suggesting trichotillomania as a possible cause of the observed alopecia. This case appears to represent an unusual clinical manifestation of SM.
多发性皮脂囊肿(SM)是一种罕见的毛囊皮脂腺单位疾病,其特征是形成许多含有皮脂的真皮囊肿,很少累及头皮。在此,我们报告一例50岁男性,头皮上有多个囊性结节和脱发斑。组织病理学检查发现,折叠的囊肿内衬复层鳞状上皮,囊壁中可见扁平的皮脂腺细胞。毛发乳头和毛囊周围区域有色素沉着,提示拔毛癖可能是观察到的脱发的原因。该病例似乎代表了SM的一种不寻常临床表现。
