Abstract

Sister Mary Joseph's nodule is a rare but significant clinical sign that often indicates advanced intraabdominal malignancy. It presents as a palpable umbilical nodule and may be the first indication of an occult primary cancer. In this article, we discuss the case of a 58-year-old postmenopausal woman who presented to a primary care clinic with a darkened umbilical lesion and progressive abdominal symptoms. She wps ultimately diagnosed with metastatic endometrial carcinoma. This uncommon presentation highlights the importance of a comprehensive approach to umbilical lesions in the primary care setting. Recognising this subtle sign in primary care can lead to expedited investigations and timely intervention.

Keywords: Diagnostic imaging; Endometrial neoplasms; Neoplasm metastasis; Primary health care; Umbilical neoplasm.
