A Rare Presentation of Endometrial Cancer recurrence with Scapular metastasis: A Case Report and Review of the Literature

Abstract

Bone metastasis from endometrial cancer is rare. Most of the early stage endometrial cancers with endometrioid histology are confined to the uterus at the time of diagnosis and confer a good prognosis. Endometrial metastases to the bone are generally restricted to the axial skeleton, including the pelvis and thoracolumbar vertebrae. Skeletal metastases in the appendicular skeleton such as scapula, clavicle and extremities to tibia, and tarsus are rarely reported. We present the case of a 50-year-old woman with diagnosis of endometrioid adenocarcinoma of the endometrium, FIGO stage IB, grade 2, with lympho-vascular space invasion who developed recurrence within 10 months with bone metastasis to left scapula and extraosseous soft tissue mass over left shoulder. There are very few cases reported in literature of scapular metastases in an early-stage endometrial carcinoma. We discuss evaluation, treatment options, overall survival rates and provide a literature review of prior published reports.
