Background: Parotid melanoma is a very rare disease. Primitive intra-parotid localization is unusual. We report the case of a patient with a parotid localization melanoma without a known primary. Case presentation: A 57-year-old woman who consulted for a progressively increasing left lateral cervical mass. A mass biopsy was performed. The histological and immunohistochemical analysis was in favor of melanoma. A complementary assessment in search of the primitive was without anomaly. The tumor is found to be unresectable after discussion of the case at a multidisciplinary consultation meeting. The therapeutic decision was to do palliative chemotherapy such as Carboplatine AUC2-Paclitaxel 80 mg/m2 J1J8J1=J21 given the deteriorated general condition of the patient. The median of overall survival was 10 weeks. Conclusion: Through this work, we have reported a rare and very aggressive case of intraparotid melanoma of unknown primary
