An Unusual Presentation of Gastric Cancer Metastatic to the Penile Shaft and Perineum.

Metastatic disease to the penile shaft is among the most rare metastatic sites for any neoplasm. We report the case of a healthy 69-year-old Jamaican male who initially presented with classical primary gastric adenocarcinoma. He was subsequently treated in a routine manner with complete surgical resection followed by chemoradiation as per the US Intergroup Trial 0116. Two years later, the patient presented with a chief complaint of dyspareunia. He was found to have a perineal nodule and penile skin thickening. He was ultimately diagnosed with gastric metastasis and treated with chemotherapy and salvage radiotherapy. He was followed up for a further 15 months but was eventually lost to follow-up and passed away.
