This case report describes the first documented instance of an extrauterine low-grade endometrial stromal sarcoma exhibiting extensive endometrioid glandular differentiation. The authors present a unique histological presentation that appeared to originate within pre-existing endometriosis, distinguishing it from previously reported cases which were exclusively uterine in origin. The paper highlights the diagnostic challenges associated with rare lesions displaying unusual morphological features. Relevance to endometriosis: This paper is centrally about endometriosis, specifically discussing the potential malignant transformation of endometriotic tissue into extrauterine endometrial stromal sarcoma.

Abstract

Endometrial stromal sarcoma of the uterus (ESS) is a rare lesion that can cause diagnostic difficulty especially when it presents with unusual histologic features such as diffuse endometrioid glandular differentiation. Only three such cases have been reported, all primary in the uterus. We report the first case of an extrauterine low-grade ESS with extensive glandular differentiation that appeared to arise in endometriosis.
