MELANOME CHOROIDIEN PRIMITIF : A PROPOS D?UNE OBSERVATION ANATOMO-CLINIQUE.

Choro?dal melanoma (CM) is the most common intraocular malignant neoplasm in adults. The diagnosis is based on histological and immunohistochemical examination.These tumors have a pejorative prognosis and their evolution is marked by the appearance of metastases especially in the liver. Currently, the development of genomic analyzes has led to a better understanding of the molecular mechanisms involved in oncogenesis. Therapeutic management has become much more difficult since the appearance of conservative treatments to keep the eye. We report a new case of choroidal melanoma in a 29-year-old patient diagnosed at the pathology department of the Mohammed VI CHU (Marrakech, Morocco). The aim of this work is to study the anatomo-clinical and evolutionary aspects of this infrequent entity.
