Melanoma Originating from the Dura-Mater: A Case Report and Review of the Literature.

Melanomas originating from the dura-mater are extremely rare tumors. The diagnosis is complex, and usually only made after excluding other entities. The prognosis is poor, with average free-disease survival of 20 months, after treatment with complete surgical excision and adjuvant therapy. We report the case of a 41-year-old asymptomatic patient, presenting with a subcutaneous mass in the left parieto-occipital region, later diagnosed as a primary dura mater melanoma. Treatment included complete microsurgical excision, radiotherapy and adjuvant immunotherapy. Therefore, due to the rare nature of the disease and its high lethality, correct diagnosis and treatment are medical challenges.
