Oral melanoma: diagnosis and treatment

Melanoma of the mouth is rare, most commonly occurring on the upper jaw of patients older than 50 years. Because of a frequent delay in diagnosis, the tumors are often diagnosed after they are deeper than the average cutaneous melanoma. Hence, the prognosis tends to be poor. Surgery is the mainstay of treatment, but often it is difficult because of anatomic restraints. Although melanoma is classically not very radiosensitive, occasional patients have had a good response to radiation therapy, sometimes with temporary palliation. Other treatment modalities are similar to those used for cutaneous melanoma. Immunotherapy, including interferon, has been used. Chemotherapy has a low response rate.
