'Primary' reticulum cell sarcoma of the retina

Because of the personal experience in 12 patients with the diagnosis of reticulum cell sarcoma of the retina, we believe that this entity is not an uncommon cause for a 'pseudouveitis'. A primary reticulum cell sarcoma of the retina must be considered in the differential diagnosis of uveitis or panuveitis if there is: (1) progression in spite of unusual antiinflammatory therapy; (2) if the initial infiltrations are seen in the deeper layers of the sensory retina and beneath the retinal pigment epithelium, and (3) if neurologic symptoms are present in patients more than age of 40. If the patients refuses methods for histologic and cytologic confirmation, the diagnoses can be made clinically.
