A 45 year old patient wad admitted with pain abdomen and a palpable mass in the epigastrium of 3 months duration. Endoscopy revealed growth in the stomach and biopsy showed poorly differentiated Carcinoma. Distal radical subtotal gastrectomy was done. Histopathology revealed choriacarcinoma with Syncytiotrophoblastic and cytotrophoblastic and foci of adenocarcinoma. Postoperatively urine and serum had very high levels of beta-human chorionic gonogotrophins (B-HCG). Immunochemistry showed positivity for B-HCG. Clinically and on scan both the testis were normal. Because of its rarity, we are presenting this case with brief review of literature.
