Prostate Cancer Metastasis to the Stomach

Prostate cancer commonly manifests with bony metastases. Visceral metastasis can also occur in the lungs and liver. However, stomach metastasis related to prostate cancer is rare. Here, we report a case of prostate cancer metastatic to the stomach. A 66-year-old male was diagnosed with prostate adenocarcinoma. He was noted as having abdominal discomfort, nausea, and vomiting 18 months after the diagnosis. A histopathologic examination and an esophagogastroduodenoscopic gastric biopsy revealed stomach-metastatic adenocarcinoma. He was also noted as having cerebellar metastatic lesions, which were identified by using a brain magnetic resonance imaging (MRI) scan. The patient died of cardiovascular complications 5 months after the diagnosis of stomach metastasis.
