Abstract
Umbilical metastasis from malignant neoplasms, the so-called Sister Mary Joseph nodule, a marker of poor prognosis, is rare. Herein, we report the case of a patient with umbilical metastasis from sigmoid colon cancer who showed prolonged survival.
A 62-year-old man presented to us with a bleeding umbilical tumor. Biopsy of the umbilical tumor revealed adenocarcinoma. Abdominal CT and colonoscopy revealed the diagnosis of sigmoid colon cancer. We performed sigmoidectomy with D3 lymph node dissection and resection of the umbilical tumor. Histopathology revealed that the tumor was type 2, pSE (depth of invasion), pN0, H0, P0, M1(umbilicus). Based on the above findings, the patient was diagnosed as having stage IV cancer of the sigmoid colon. Adjuvant chemotherapy was administered, and the patient has remained well without recurrence for over 3 years.
