Sister Mary Joseph's Nodule as a Cutaneous Expression of Metastatic Pancreatic Adenocarcinoma.

A Sister Mary Joseph's nodule (SMJN) is characterized by a palpable umbilical nodule and is often a clinical indicator of the metastasis of an advanced abdominal or pelvic malignancy. Observing the cutaneous manifestation of an abdomino-pelvic malignancy is a relatively rare phenomenon due to the appearance of visible changes in the later stages of the disease. With the pancreas being a less common primary tumor site for SMJN, this case report describes a 57-year-old male diagnosed with metastatic pancreatic adenocarcinoma with a SMJN.
