Three patients, each more than 60 years of age at initial presentation, had early stage lymphoid infiltrates (formerly called reactive lymphoid hyperplasia) of the choroid and contiguous extraocular tissues. There were multifocal, confluent, and nonconfluent creamy patches in the choroid. These lesions changed very little over periods of observation ranging from 1 to 4 years and failed to produce ophthalmoscopically visible disturbances of the retinal pigment epithelium (RPE). Fluorescein angiography demonstrated dye collection within the lesions without leakage into the subretinal or subpigment epithelial spaces. Both ultrasonography and computed tomography (CT) showed thickening of the choroid with either anterior or posterior episcleral extensions of lymphoid tissue. Pathologic evaluation of biopsy specimens of extraocular portions of the lesions showed low-grade tumors that were diffuse infiltrates of mature lymphocytes, which exhibited lymphoplasmacytoid features, Dutcher bodies, or small residual germinal centers (so-called borderline lesions). Two patients had uniocular localized disease, whereas the third had bilateral ocular lesions, hypogammaglobulinemia, and another extranodal chest wall lymphoid tumor. Therapy for the localized ocular condition consisted either of oral administration of corticosteroids or low doses of radiotherapy.
