A case of adenomatoid tumor arising from the epididymis is reported. A patient visited our hospital with complaint of a painless intrascrotal mass. Preoperative diagnosis was right epididymal tumor. Right epididymectomy was performed and histological diagnosis was adenomatoid tumor of the epididymis. We examined the histogenesis of this case by the immunoperoxidase technique. The tumor revealed cytoplasmic staining of tubular lining cells for keratin with no staining for myoglobin. This finding supported a mesothelial rather than endothelial derivation for this tumor. We found no muscle elements in this tumor.
报告一例起源于附睾的腺瘤样瘤。一名患者因阴囊内无痛性肿块前来我院就诊。术前诊断为右侧附睾肿瘤。行右侧附睾切除术，组织学诊断为附睾腺瘤样瘤。我们采用免疫过氧化物酶技术检查了该病例的组织发生。肿瘤显示管状内衬细胞的细胞质对角蛋白呈阳性染色，对肌红蛋白无染色。这一发现支持该肿瘤起源于间皮而非内皮。我们在该肿瘤中未发现肌肉成分。
