A positive urine pregnancy test with haemoperitoneum: misdiagnosed postpartum choriocarcinoma with uterine rupture mimicking ruptured ectopic pregnancy.

Objectives: Choriocarcinoma after a term pregnancy is rare and can be life-threatening, especially when it perforates the uterus, resulting in massive haemoperitoneum. As uterine rupture due to choriocarcinoma is uncommonly encountered in the clinical practice, its diagnosis is often missed or delayed.

Case Presentation: We present a case of a 41-year-old para 4 + 1 who had acute abdomen and hypovolaemic shock secondary to haemoperitoneum at three months postpartum period.
