A DARK UMBILICAL NODULE IN A POSTMENOPAUSAL WOMAN: WHAT IS YOUR DIAGNOSIS? Sister Mary Joseph’s nodule is a rare but significant clinical sign that often indicates advanced intra- abdominal 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 was 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.

Uterine leiomyosarcoma is a malignant smooth muscle tumour of the uterus. It is rare and accounting for less than 2% of cases in malignant gynaepathology. To date, only a few reported cases of leiomyosarcoma arising from leiomyoma documented in the literature. We shared an uncommon occurrence of leiomyosarcoma arising from leiomyoma. Presented herein is a case of a ‘rare epithelioid subtype’ of leiomyosarcoma arising from a leiomyoma in a postmenopausal woman. We highlighted the importance of recognizing the possibilities of this event to allow for a timely diagnosis of leiomyosarcoma and to provide insights on management of patients presented with clinically presumed fibroid.
