摘要

Primary uveal lymphoma is rare and, unlike the vitreoretinal lymphomas, is typically indolent in nature [1-3]. In the past these tumors were termed 'reactive lymphoid hyperplasia' or 'uveal pseudotumor' because of their low-grade appearance [4-6]. However, convincing evidence with modern techniques has demonstrated that the majority of these lesions are low-grade B-cell lymphomas, most commonly extran-odal marginal zone B-cell lymphomas [1, 5, 7] according to the current WHO classification (table 1) [8]. Primary high-grade lymphomas involving the uvea are extremely rare [26]. Uveal lymphoma may be considered primary if the uvea is the only or the initial site and secondary if there is secondary involvement of the uvea by systemic non-Hodgkin lymphoma [13, 27-34]. Hence, a careful clinical evaluation for involvement of other sites is required at the time of initial diagnosis and subsequent follow-up.
