In [[medicine]], the '''Sister Mary Joseph nodule''' or '''node''', also called '''Sister Mary Joseph sign''', refers to a palpable nodule bulging into the [[umbilicus]] as a result of [[metastasis]] of a malignant cancer in the pelvis or abdomen.
Gastrointestinal malignancies account for about half of underlying sources (most commonly [[gastric cancer]], [[colonic cancer]] or [[pancreatic cancer]], mostly of the tail and body of the pancreas<ref name="pancreas">Yendluri V, Centeno B, Springett G. Pancreatic cancer presenting as a Sister Mary Joseph's nodule: case report and update of the literature. ''Pancreas''. 2007;34(1):161-4. PMID 17198200</ref>), and men are even more likely to have an underlying cancer of the gastrointestinal tract. Gynecological cancers account for about 1 in 4 cases (primarily [[ovarian cancer]] and also [[uterine cancer]]). Unknown primary tumors and rarely, urinary or respiratory tract malignancies cause umbilical metastases.<ref name="GalvaƱ">GalvaƱ VG. Sister Mary Joseph's nodule.

Proposed mechanisms for the spread of cancer cells to the umbilicus include direct [[peritoneum|transperitoneal]] spread, via the [[lymphatics]] which run alongside the obliterated [[umbilical vein]], hematogenous spread, or via remnant structures such as the [[falciform ligament]], [[median umbilical ligament]], or a remnant of the [[vitelline duct]].<ref name="Medscape">Cohen, DC.
