Abstract
- A primary genitourinary melanoma is rare, accounting for less than 1% of all cases of melanoma. They have been presented in case reports, with a subsequent paucity of insight into the natural history of the disease and appropriate management of patients. The prognosis of patients with a genitourinary melanoma is poor. Delay in seeking medical attention for symptoms, and misdiagnosis at presentation, contribute to a more advanced stage at diagnosis. Our case involved a 71 year old woman, who came to our hospital due to vaginal spotting. On local excision, mass was found on the vestibule and forward to the urethra. The pathological diagnosis, by special immunohistochemical staining, such as S-100 protein and HMB-45, was that of a malignant melanoma.
