title: [Case of primary malignant melanoma of the female urethra at age 94 : a case report].
abstract: A 94-year-old woman visited a local urological clinic in January 2011 complaining of dysuria and vulvar discomfort that lasted for a month. Clinical examination showed a hematoma-like tumor at the external urethral meatus. She refused an operation. After 2 months, the tumor became hemorrhagic and she was referred to our hospital for operation. A black tumor of fingertip-size was seen at the external urethral meatus. Urinary sediment examination and urine cytology revealed malignant melanoma cells. The tumor showed T1WI high intensity, and T2WI low intensity by magnetic resonance imaging. Collectively, the patient was diagnosed with malignant melanoma. The tumor was extirpated. Pathological diagnosis showed malignant nodular melanoma. However, additional therapy was not performed due to her age and thereafter, the patient was followed up carefully. After 3 months, right inguinal LN swelled, and tumor recurred at the external urethral meatus. She died from multiple metastases 11 months from the initial consultation. We herein report this case of primary malignant melanoma of the female urethra in an elderly patient.
