uterine tumour resembling ovarian sex cord tumour (UTROSCT)肌源性标记物常常阳性,CD10常常阴性。但上皮性标记物(AE1/AE3 EMA)以及性索间质肿瘤标记(inhibin/calretin/CD99)常常有表达,此例形态像UTROSCT,但CK阴性让人有点犹豫,建议再做EMA和inhibin等标记物看看。
J Clin Pathol. 2006 Dec 20;Uterine tumour resembling ovarian sex cord tumour is an immunohistochemically polyphenotypic neoplasm which exhibits coexpression of epithelial, myoid and sex cord markers.
可能是epithelioid smooth muscle tumor。rule out PECOma with HMB45.
some areas have alveolar-like pattern or pseudoalveolar pattern and some cells have rhabdoid-like appearance but i do not see any mitotitic figures. Also pure rhabdomyosarcomas are so rare. just put this entity in the differential diagnosis.
谦谦君子学习并尝试翻译如下:
可能是上皮样的平滑肌肿瘤,可用HMB45染色排除一下PECOoma(Neoplasms with perivascular epithelioid cell differentiation 上皮样细胞分化的血管周肿瘤)。 一些区域有小囊样或假囊样形态,一些细胞有横纹肌样形态,但我没有看到核分裂。单纯的横纹肌肉瘤是很少见的,需要鉴别诊断。 |
