Sister Mary Joseph nodule in colorectal cancer.

Abstract

Sister Mary Joseph nodule is the umbilical metastasis detected in cancer patients. There are various theories on the formation of umbilical metastases; however, the primary focus is often placed either in the abdomen or pelvis. Its prognosis is dismal. In this article, we aimed to present a 44-year-old male patient who presented with obstruction and was subsequently diagnosed with colorectal cancer and umbilical metastasis.
