[A case of secondary Paget's disease of the glans penis originating from bladder cancer].
An 81-year-old man had undergone total cystectomy and bilateral ureterocutaneostomy at the age of 66 years. Furthermore, no recurrence or metastasis was observed; but at the age of 80 years he observed a painless rash around the external urethral orifice. As urothelial cancer was suspected, the urethra and glans were biopsied. Through immunohistochemical staining (cytokeratin 7 and 20), the glans biopsy indicated secondary Paget's disease of transitional epithelial origin. A urethrectomy was performed as progression from the urethra was suspected. The pathological examination revealed Paget cells at the glans, but the tumor was not observed permeating into the corpus cavernosum. This presents a rare case of secondary Paget's disease originating from a bladder tumor, and appearing in the glans without intraurethral progression.
