[Surgical Resection as Local Therapy for Sister Mary Joseph's Nodule Due to Pancreatic Tail Cancer].

We experienced a case of resection of a metastatic umbilical tumor(Sister Mary Joseph's nodule: SMJN)derived from a pancreatic tail carcinoma. The patient was a 70-year-old woman. She visited her previous doctor with a chief complaint of lower abdominal pain and came to our hospital due to suspicion of pancreatic tail cancer. She was found to have metastases to multiple organs which was unresectable by surgery. After chemotherapy up to the second-line of treatment, she was diagnosed to have progressive disease. The decision was made to provide the best supportive care for the patient. Thereafter, the patient developed SMJN. She had hemorrhage from the tumor accompanied by body movement, and her activity of daily living became impaired. She had difficulty controlling the bleeding despite repeated hemostatic treatment at the outpatient clinic and at her home. However, she required frequent blood transfusions for her severe anemia. Therefore, we performed a resection of the SMJN to control bleeding and to relieve her symptoms. She had a good postoperative course and was discharged on the fifth postoperative day. Due to deterioration of her general condition, she expired on the 59th day after surgery. However, the patient was able to live at home without bleeding or pain by the umbilical tumor. The local resection was considered to be useful as a palliative surgical treatment for SMJN.
