Sister Mary Joseph's nodule: a rare cytologic presentation

Umbilical metastasis is one of the main characteristic signs of extensive neoplastic disease and is universally referred to as Sister Mary Joseph's nodule. It indicates neoplasm of inner organs mostly located in the gastrointestinal tract or the pelvis. However, in approximately 15-30% the primary tumor remains occult. In most cases, Sister Mary Joseph's nodule appears as an early and sometimes the only symptom of the malignancy. Here we report a rare fine needle aspiration (FNA) cytologic diagnosis of umbilical metastasis of an ovarian carcinoma.
