Ocular involvement by non-Hodgkin's lymphoma is a rare condition that can result from a primary intraocular lymphoma of the retina or an intraocular manifestation of systemic lymphoma. Uveal involvement is seldom the initial manifestation of extranodal lymphoma. We describe an 80-year-old patient with a blind and painful left eye and a history of recurrent uveitis. After ultrasound evaluation, the eye was enucleated and histopathologic examination revealed a malignant B-cell lymphoma of the uveal tract. The patient has been followed for 8 years after surgery, but she has had no further systemic manifestations of lymphoma and has not required subsequent treatment. ⋯ Primary extranodal lymphoma can be easily mistaken for recurrent uveitis or primary intraocular lymphoma of the retina and central nervous system; it is a differential diagnosis to be considered in cases of recurrent uveitis-like symptoms evolving to blind painful eye.
