non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...

Ocular involvement in lymphoma is a relatively rare condition that can result from a primary intraocular lymphoma or an intraocular manifestation of systemic lymphoma. Lymphoma manifestations frequently masquerade as other more benign intraocular conditions including allergic or infectious conjunctivitis, uveitis, multiple evanescent white dot syndrome, acute retinal necrosis, or herpetic retin...

Primary intraocular lymphoma is almost always a central nervous system B-cell non-Hodgkin lymphoma. Primary intraocular lymphoma is commonly diagnosed by demonstrating lymphoma cells in the vitreous or cerebrospinal fluid. An interleukin (IL) 10 to IL-6 ratio greater than 1.0 in these fluids and the detection of immunoglobulin gene rearrangement are useful adjuncts in the diagnosis of primary i...

Primary intraocular lymphoma (PIOL) is an ocular malignancy that is a subset of primary central system lymphoma (PCNSL). Approximately one-third of PIOL patients will have concurrent PCNSL at presentation, and 42-92% will develop PCNSL within a mean of 8-29 months. Although rare, the incidence has been rising in both immunocompromised and immunocompetent populations. The majority of PIOL is dif...

PURPOSE To report a case of bilateral primary intraocular lymphoma. CASE REPORT A 33-year-old man presented with bilateral blurred vision since two years ago. Examination revealed large keratic precipitates, anterior chamber reaction, posterior subcapsular cataracts, and vitreous infiltration. After a short trial of topical and periocular steroids, diagnostic 25-gauge pars plana vitrectomy wa...

Background. The ocular adnexal region is the primary localization of extranodal lymphoma in 5% to 15% of all NonHodgkin lymphoma. Intraocular lymphoma of T-cell origin is extremely rare and such sites of infiltration have been rarely observed in clinical examination. Case report. We presented a 56-year-old man with iris infiltration by primary intraocular peripheral T-cell lymphoma. The patient...
