This case report describes a rare instance of ovarian adenosarcoma developing within an endometriotic cyst in a patient who was not using hormonal therapy. The tumor exhibited extensive deciduoid morphology throughout its mesenchymal component, a histological feature that had not been previously documented in this context. The authors discuss the differential diagnosis and propose potential pathogenic mechanisms for this unusual stromal alteration. This paper is centrally about endometriosis — specifically as the precursor lesion from which a rare malignant transformation into adenosarcoma occurred.

Abstract

A case of müllerian adenosarcoma arising in ovarian endometriosis is reported in which the whole of the mesenchymal component exhibited striking deciduoid morphology, a phenomenon that has not been previously described. The patient was not taking hormonal preparations. We discuss the differential diagnosis and the possible pathogenesis of the deciduoid stromal alteration.
