title: Penile malignant melanoma in a hemodialysis patient.
abstract: A patient who was receiving hemodialysis treatment developed melanotic macules on the surface of the penis in 2002 and showed a tumor-like mass in the same region in July 2006. The patient presented with a pedunculated tumor of 3 cm in diameter on the right side of his penis. The tumor was resected for biopsy and was diagnosed as malignant melanoma. The melanoma was in stage IIIB with pT4 N1 M0. The patient received interferon-beta for a total of three courses. A computed tomography scan in the 10th postoperative month did not find any additional metastatic foci or recurrence of the tumor. In the present case, side effects caused by interferon were not observed. Therefore, particularly in dialysis patients, immune therapy might be favored over anticancer drug treatment.
