Aetiology
Melanoma of the penis is a rare form of cancer that affects the skin of the penis. It is most commonly seen in males aged 50-70, and it is caused by ultraviolet light exposure, especially in uncircumcised males. Other risk factors include a history of genital warts, and a weakened immune system.
Diagnosis
Melanoma of the penis is usually diagnosed through physical examination, or by biopsy. The doctor may take a sample of the skin from the penis and examine it under a microscope to look for cancer cells.
Differential diagnosis
Other conditions that may be mistaken for melanoma of the penis include benign lesions such as moles or freckles, and other skin conditions such as lichen planus.
Treatment
Treatment for melanoma of the penis may include surgery to remove the affected area of skin, radiation therapy, and chemotherapy.
Prognosis
The prognosis for melanoma of the penis depends on the stage of the cancer when it is diagnosed. Early stage melanomas can be cured with treatment, however more advanced cases may be more difficult to treat.
