We report a case of an epidermoid cyst arising on the upper chest that had a remarkable histologic pattern composed of structures resembling eccrine ducts in the horny layer and an acrosyringium. The expression of carcinoembryonic antigen (CEA) was also demonstrated immunohistochemically within these ductal structures. Eccrine ducts have been reported recently, in epidermoid cysts located in the palmoplantar region. The cyst described here suggests that epidermoid cysts derived from eccrine ducts may also appear on the torso.
我们报告一例发生于上胸部的表皮样囊肿，其具有显著的组织学模式，由角质层中类似小汗腺导管的结构和顶泌汗腺导管组成。免疫组织化学检测还显示这些导管结构内存在癌胚抗原（CEA）表达。最近有报道称，位于掌跖区域表皮样囊肿中存在小汗腺导管。此处描述的囊肿提示，源自小汗腺导管的表皮样囊肿也可能出现在躯干上。
