Abstract
•Endometrial stromal sarcoma (ESS) may have sex cord differentiation, usually focal.•Diagnosis of ESS is difficult when variant morphology predominates.•Prognosis differs between ESS and UTROSCT; therefore, distinction is critical.•Extensive tumor sampling is mandatory to identify neoplastic endometrial stroma.•Sex cord differentiation may be associated with endometrial hyperplasia.
摘要
•子宫内膜间质肉瘤（ESS）可能具有性索分化，通常为局灶性。
•当变异形态占主导时，ESS的诊断较为困难。
•ESS和子宫未分化肉瘤（UTROSCT）的预后不同；因此，鉴别至关重要。
•必须进行广泛的肿瘤取材以识别肿瘤性子宫内膜间质。
•性索分化可能与子宫内膜增生有关。
