Abstract
A positive urine pregnancy test (UPT) with adnexal mass in ectopic pregnancy is not the ultimate diagnosis. The incidence of ectopic pregnancy is about 27 per 1000 pregnancies [1]. On average, about 6–16% will present to an emergency department with first-trimester bleeding and abdominal pain [2]. On presenting with these symptoms with the simultaneous presence of an adnexal mass and an empty uterus, a UPT is of paramount importance to determine whether the symptoms are pregnancy related or not. When the UPT is positive, an ectopic pregnancy is not the only diagnosis as the rare entity of non-gestational ovarian choriocarcinoma (NGOC) should be considered. Here we present two case reports of NGOC, which were initially diagnosed as ectopic pregnancy. The first case is a 16-year-old girl, with vaginal bleeding and an adnexal mass due to an ovarian choriocarcinoma, She underwent unilateral oophorectomy and received multiple courses of chemotherapy. She is disease free without evidence of recurrence or metastasis after 12 months of follow-up. The second patient is also 16 years old and presented with an acute abdomen. She was diagnosed as a ruptured luteal cyst and underwent partial oophorectomy. When the pathologist diagnosed a choriocarcinoma she received multiple courses of chemotherapy, but thereafter an advanced disease was diagnosed with evidence of distant metastasis.
