摘要 目的探讨胎盘部位滋养细胞肿瘤(placental site trophoblastic tumor,PSTT)、上皮样滋养细胞肿瘤(epithelioid trophoblastic tumor,ETT)、胎盘部位过度反应(exaggerated placental site,EPS)及胎盘部位结节(placental site nodule,PSN)4种中间型滋养细胞(intermediate trophoblast,IT)疾病临床病理特征及鉴别诊断要点。方法收集10例IT疾病标本,结合患者临床表现、肿物形态学特征及免疫表型,观察并总结鉴别诊断要点。结果 PSTT与ETT为肿瘤性病变,具有侵袭子宫平滑肌的特性,组织坏死常见;EPS与PSN为非肿瘤性病变,常见于刮宫活检标本,有时易误诊为肿瘤。4种病变免疫组化标记均表达上皮及滋养细胞标志物,PSTT及EPS中HPL呈弥漫阳性,ETT及PSN中p63呈弥漫阳性。结论 PSTT、ETT、EPS及PSN均为少见的IT疾病,滋养叶细胞形态特征和免疫表型有助于鉴别诊断。
