A case of colon cancer associated with schistosomiasis japonica is reported. A 60-year-old man was admitted with the complaint of melena. Barium enema study revealed a colon tumor (type 1') 11 cm from the anal ring. Sigmoidectomy was performed, and no lymph node metastasis was observed. Histologically, the tumor was diagnosed as well-differentiated adenocarcinoma, and also many schistosoma ova were found not only in the lesion of the carcinoma, but also in the tissue surrounding the carcinoma. In the latter lesion, ova were observed beneath muscularis mucosae. The distributions of the ova in the anal side of the tumor were more dominant than those in oral side. We review the direct correlation between gastrointestinal tract cancer and the schistosomiasis japonica in other reports.
报告一例与日本血吸虫病相关的结肠癌病例。一名60岁男性因黑便主诉入院。钡灌肠检查发现距肛门环11厘米处有一结肠肿瘤（1'型）。行乙状结肠切除术，未观察到淋巴结转移。组织学上，肿瘤被诊断为高分化腺癌，并且不仅在癌灶中，而且在癌灶周围组织中也发现了许多血吸虫卵。在后者的病变中，卵见于黏膜肌层下方。肿瘤肛门侧的卵分布比口腔侧更占优势。我们回顾了其他报告中胃肠道癌与日本血吸虫病之间的直接相关性。
