Cutaneous metastasis into the umbilicus, known as a Sister Mary Joseph nodule, is quite rare. Gastric adenocarcinoma is the most common primary origin overall, whereas gynecologic tumors such as ovarian cancer are the leading cause in women. In most cases, the nodule manifests after the primary tumor had been diagnosed. In rare cases, however, it serves as the first sign of the underlying malignancy. Here, we report the case of a 59-year-old woman who presented with a nodule on the umbilicus and was diagnosed with metastatic adenocarcinoma originating in the gallbladder.
