Primary choriocarcinoma of the stomach presenting as gastrointestinal hemorrhage: report of a case.
A case of primary choriocarcinoma of the stomach presenting as gastrointestinal hemorrhage in a 58-year-old postmenopausal woman is presented. Arteriographic features included a large hypervascular gastric mass and multiple liver masses with vascular poolings, mimicking those of cavernous hemangioma. Postcontrast CT including delayed scan showed a large central nonenhanced area with marginal peripheral contrast enhancement. Close observation of the angiographic findings revealed peripheral vascular poolings and central avascularity, which are characteristic of uterine choriocarcinoma. Human chorionic gonadotrophin (HCG) titer was significantly elevated, and extragenital choriocarcinoma of the stomach was confirmed by autopsy.
