Choriocarcinoma is part of a rare spectrum of placental abnormalities known as gestational trophoblastic disease (GTD). It is the most invasive form of GTD, with a mortality rate approaching 100% if left untreated. It spreads predominantly hematogenously to multiple target sites, most commonly the lungs. Due to its hypervascular nature, it is often complicated by bleeding. We describe a case of choriocarcinoma in a 40-year-old female with metastases to the lungs, brain, and bilateral kidneys resulting in large retroperitoneal hematomas.

绒毛膜癌是一种罕见的胎盘异常疾病，属于妊娠滋养细胞疾病（GTD）范畴。它是GTD中侵袭性最强的一种，若不治疗，死亡率接近100%。它主要通过血行转移至多个靶器官，最常见的是肺部。由于其血管丰富的特性，常伴有出血并发症。我们报告一例40岁女性绒毛膜癌病例，该患者发生了肺、脑及双侧肾脏转移，并导致巨大的腹膜后血肿。
