[A Surgically Resected Case of Lung Metastases and Sister Mary Joseph's Nodule 24 Months after Operation for Pancreatic Cancer].

Le résumé fourni par la source

Metastatic umbilical tumors from internal malignancy, known as Sister Mary Joseph's Nodule(SMJN), are a relatively rare prognostic sign. An 86-year-old woman with pancreatic body carcinoma underwent distal pancreatectomy for D2 lymph node removal in 20XX. No peritoneal dissemination was found at that time. Postoperative chemotherapy was not administered due to her age. Eighteen months postoperatively, tumor marker values increased and chest computed tomography(CT) revealed a single mass in the left lung. We resected the suspected lung metastasis. Positron emission tomography-CT performed 23 months postoperatively for increased tumor marker values after resection showed a 18F-fluorodeoxyglucose accumulation ofapproximately 4 cm in the umbilicus. The diagnosis by biopsy was umbilical metastasis ofthe pancreatic cancer. No recurrence or other metastases were found, so we performed an umbilical tumor resection and abdominoplasty 24 months postoperatively. No peritoneal dissemination was found in her abdomen and the ascites cytology was negative. The tumor was in the subcutaneous tissue; thus, the possibility of infiltration from the primary site or peritoneal dissemination was low. The tumor marker values decreased after the resection. She was followed-up without postoperative anticancer chemotherapy. However, the tumor marker values increased again, so chemotherapy was initiated. We report a case ofresection of pancreatic cancer and operation for lung and umbilical metastases of pancreatic cancer.
