Prostate carcinoma metastatic to the stomach: report of two cases and review of the literature.

We report two cases of prostate carcinoma metastatic to the stomach. In the first case, the patient had indolent disease before presenting with gastric metastasis. The patient responded to treatment with resolution of gastrointestinal bleeding and other symptoms. In the second case, the patient developed aggressive prostate carcinoma while on immunosuppressive therapy following kidney transplant. His tumor became widely systemic, and he ultimately died of his disease. Although rare, the possibility of prostate carcinoma metastatic to the stomach should be considered when a patient with a history of prostatic adenocarcinoma presents with gastrointestinal symptoms.
