Sister Mary Joseph's Nodule as a First Manifestation of Primary Peritoneal Cancer

الملخص EN

Sister Mary Joseph's nodule metastasis is a rather rare finding.

The primary malignancy in women is usually ovarian, endometrial, gastric, or pancreatobiliary tree cancer.

We present a case of an 87-year-old patient with Sister Mary Joseph's nodule metastasis caused by a primary peritoneal malignancy.

Through a literature search, we also discuss the pathophysiology, diagnostic approach, management, and prognosis of such a condition.
