Metastatic urothelial carcinoma of the urethra and glans penis with reported implantation via the urine: A case report.

Urothelial carcinoma accounts for the vast majority of diagnosed bladder cancer cases. Urothelial carcinoma is prone to recurrence and metastasis despite complete resection of the lesions. The present case report describes a patient who underwent cystoprostatectomy due to a diagnosis of recurrent bladder cancer, with a penile lesion found several years after surgery. A partial penectomy was performed and the subsequent histopathology result showed urothelial carcinoma of the urethra and the epithelium of the glans and foreskin nested by micturition. The present case is an extremely rare incidence of the spread of cancer through the urine. To date, only a few such cases have been reported in the literature.
