Introduction. The primitive malignant melanoma of nasal mucosa and paranasal sinus is a rare tumor of uncertain etiology, with unpredictable biologic behavior and bad prognosis. Unlike skin melanomas, there are no risk factors and the disease is frequently manifested in older patients, whose clinical otorhinolaryngology complaints are normally non-specific and ranges from nasal obstruction to rhinorrhea and epistaxis. Unfortunately, this disease is diagnosed basically in advanced stages which makes the surgery difficult. Objective. To report a case of primitive malignant melanoma of nasal mucosa, ethmoid and frontal sinuses, that was diagnosed in 2015. It was performed a subtotal resection in another hospital in 24.08.2015, with a large local reccurence. Report. Our patient was a 78-year-old woman with bilateral nasal obstruction, light epistaxis and unilateral rhinorrhea. The ENT, CT and MRI exams showed a tumour with important, invasion of the nasal cavity structures (billateral nasal bones, left frontal process of the maxilla, the superior midpoint of the nasal septum, bilateral middle and superior turbinates, left ethmoid and bilateral frontal sinuses). The patient was submited for surgery: total macroscopic resection in the combined endoscopic approach; transnasal and modified lateral rhinotomy with titaniul plates reconstruction of the external nose architecture. Conclusions. Malignant melanomas of nasal mucosa are, in general, diagnosed in advanced stages. Their histological characteristics in the mucosa makes difficult the surgical treatment, which is one of the most efficient options, because they are resistant to chemo and radiotherapy. The early diagnosis and a good surgical treatment plan are the best option for this tumor nowadays.
