Abstract:
An autopsy case of high-grade endometrial stromal sarcoma (ESS) is reported. Immunohistochemical study of the ESS was done in comparison with carcinosarcoma (CS), leiomyosarcoma (LMS) and normal endometrium in the uterus in order to trace the origin of ESS, which is a point of some controversy. Co-expression of keratin and vimentin and/or desmin positivity in several elements of CS and LMS, and glandular or stromal tissues in normal endometrium made it difficult immunohistochemically to be certain of the origin of ESS.
