[Primary ocular lymphoma manifesting as anterior uveitis. Apropos of a case]

We report the case of a primitive ocular lymphoma occurring in a 48 year old patient. Non-Hodgkin's lymphomas are usually found in ocular localizations, and are often associated with a lymphomatous cerebral affection. The most frequent mode of presentation of these rare intra ocular tumors is usually posterior uveitis with chorioretinal lesions, and must be suspected for every long-standing chronic uveitis, especially posterior ones. The diagnosis can only be based on histological or cytological analysis. Our patient presented a primary ocular lymphoma which was initially revealed by an anterior uveitis and had evolved into a panuveitis that was resistant to treatment. The initial checkup of this uveitis remained negative and did not allow for an etiological diagnosis. The eye came less operational, hypertonic crisis became more frequent and controlled less and less by the treatment, therefore the patient had to be enucleated in order to establish a diagnosis and for therapeutic reasons. The histology revealed the existence of a NK lymphoma.
