Primary gastric chorioadenocarcinoma

ABSTRACT

Primary gastric chorioadenocarcinoma [PGC] is a rare and rapidly invasive tumor. Choriocarcinoma is usually known to be of endometrial origin and gestational; however, it has been reported in other extragenital organs, such as the gall bladder, prostate, lung, liver, and the gastrointestinal tract. Human chorionic gonadotropin related neoplasms of the stomach are seldom discussed in the literature. We report a case of PGC in a 56-year-old man treated with a standard non-gestational choriocarcinoma chemotherapy regimen, EMA/CO [etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine], with a complete response and good tolerability
