Primary choriocarcinoma of the colon is exceedingly rare. Only two cases have been previously reported, both located in the sigmoid colon. A case of choriocarcinoma arising in association with adenocarcinoma of the ascending colon (cecum) in a 35-year-old woman is described. Immunoperoxidase staining showed beta-human chorionic gonadotrophin to be present in the choriocarcinomatous portion of the primary tumor and in the metastases. Theories concerning the histogenesis of this rare neoplasma are briefly reviewed.
原发性结肠绒毛膜癌极为罕见。此前仅报道过两例，均位于乙状结肠。本文描述了一例35岁女性升结肠（盲肠）腺癌合并绒毛膜癌的病例。免疫过氧化物酶染色显示，β-人绒毛膜促性腺激素存在于原发性肿瘤的绒毛膜癌部分及转移灶中。本文简要回顾了关于这种罕见肿瘤组织发生的理论。
