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。 |
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。
