title: [Primary duodenal choriocarcinoma presenting as massive intestinal bleeding and metastasis to brain].
abstract: Duodenal choriocarcinoma, either primary or metastatic, is very rare. Early diagnosis and prompt initiation of chemotherapy improve the prognosis of this neoplasm. We herein present, together with the referred literatures, a case of a 47-year-old female patient who visited to our hospital with upper intestinal bleeding. She was diagnosed as duodenal choriocarcinoma by operation. Brain metastasis was found soon after the operation and combination chemotherapy was done.
