Sister Joseph umbilical nodule coexisting with endometriosis from endometrial carcinoma.

A 58-year-old woman was diagnosed with endometrial carcinoma. Total hysterectomy, bilateral salpingo-oophorectomy and paraaortic and a pelvic lymph node dissection were performed. The cytology of peritoneal fluid was negative. There was no peritoneal dissemination except umbilical nodule. A peritoneal 2.0x1.5 cm umbilical nodule was also resected. The nodule was identified as a metastasis from endometrial cancer with endometriosis. The pelvic lymph nodes also showed metastatic lesion with endometriosis. Our case showed that endometriosis coexisted with umbilical and pelvic lymph nodal metastatic lesions from endometrial cancer. This fact suggests that the mode of metastasis to the umbilicus via lymph flow from endometrial cancer is the same as that for endometriosis.
