Abstract
A 66-year-old man presented with macrohematuria. Cystoscope examination found a 5 mm nodular tumor at external urethral orifice and multiple papillary tumors at fossa navicularis of urethra; those are non-black colored. Transurethral resection of the urethra tumor was performed, and pathologically diagnosed as malignant melanoma. Image examinations showed no lymphadenopathy and metastasis. Accordingly, total penectomy was conducted to remove the remaining tumors, resulting in surgically curative resection. After the operation, monthly interferon-β injection into inguinal region has been administered as adjuvant therapy, resulting in no recurrence at 6 months after penectomy.
