Secondary squamous cell carcinoma of the prostate is quite rare. A 63-year-old man presented with complaint of bladder tamponade. During the examination of the origin of huge hemorrhage, we recognized the mucosa change of urethra with white patch. After the prostate biopsy, trans urethral coagulation was performed to hemorrhagic lesion. The pathological findings were SCC. In his medical history, there was total esophagectomy for esophageal carcinoma at the age of 61 years. There were multiple metastatic lesions. Therefore, we reached the diagnosis of secondary squamous cell carcinoma of the prostate. Any treatment was rejected and he died of pulmonary insufficiency two months later.
