一名57岁的女性被诊断为直肠癌。钡灌肠检查显示直肠乙状结肠有苹果核征象，结肠镜检查显示有一个被包围的溃烂肿瘤。计划在腹腔镜辅助下切除直肠；然而，直肠癌直接侵犯子宫体。手术改为开放手术。发现腹膜反射部位疑似腹膜扩散的弹性硬肿瘤，并将直肠与腹膜反射下方的直肠一并切除。肿瘤的组织学检查显示，浆膜侧可见由非粘液性柱状上皮细胞排列的囊状腺，并嵌入直肠的适当肌肉中。这个肿瘤性病变被诊断为子宫内膜异位症。
A 57-year-old woman was diagnosed as having rectal cancer. A barium enema study showed the apple-core sign at the rectosigmoid colon, and colonoscopy revealed an encircled ulcerated tumor. A laparoscope-assisted resection of the rectum was planned; however, the rectal cancer directly invaded the uterus body. The operation was converted to open surgery. An elastic hard tumor suspected of being peritoneal dissemination at the peritoneal reflection was detected and excised together with the rectum below the peritoneal reflection. A histological examination of this tumor revealed that cystic glands lined by nonmucinous columnar epithelial cells were seen on the serosal side and were embedded in the proper muscle of the rectum. This tumorous lesion was diagnosed as endometriosis.
