    【摘 要】胎盘部位滋养细胞肿瘤(placental site trophoblastic tumor，PSTT)是临床较罕见的一种妊娠滋养细胞疾病，其来自胎盘种植部位，与侵蚀性葡萄胎和绒癌相比，其病理形态、病程进展及治疗方式的选则均不同。常见症状为阴道不规则流血及无明显诱因的停经，多继发于流产、葡萄胎或足月妊娠后，体征为子宫均匀性或不规则增大，因其症状体征不典型，容易误诊。血清人绒毛膜促性腺激素(hCG)可升高或正常。PSTT绝大多数发生于生育期年龄，平均发病年龄为31岁～35岁，绝经后较为罕见。因超声检查无特异性表现，故其确诊主要靠组织病理学。现将我院收治的1例PSTT患者相关情况总结成文，结合其他研究及报道，整理探讨该病的临床特征、诊断、治疗等相关要点，以期为以后临床诊治提供可靠信息。
