[Malignant nasosinusal melanoma: apropos of a case]

We present a case of a nasosinusal malignant melanoma with a really fulminant evolution, as the patient died two and a half months after the diagnostic biopsy and five months after the initial symptoms. A bibliographic review of these rare tumours is realized, and those data of the world literature we could reach concerning to incidence, clinic features, histopathology, diagnosis, treatment, and prognosis, are analyzed.
