Purpose: To describe the clinicopathologic features of two patients with Epstein-Barr virus (EBV) associated conjunctival lymphocytic infiltrates.
Design: Two case reports.
Methods: The clinical histories and pathologic findings of two patients with salmon-colored conjunctival infiltrates are described.
Main outcome measurements: Clinical observation and pathologic examination of conjunctival biopsy specimens with accompanying immunohistochemical staining, flow cytometric immunophenotyping, and polymerase chain reaction analysis when appropriate.
Results: One patient had ipsilateral preauricular lymphadenopathy, elevated serum EBV titers, and a unilateral reactive lymphocytic infiltrate resulting in a conjunctival mass. The other patient had bilateral conjunctival lymphocytic infiltrates causing conjunctival masses. There was an expanded clonal population of B lymphocytes in the conjunctival mass in the second patient. Both patients had EBV antigen in their conjunctival lymphocytic infiltrates.
Conclusions: Conjunctival lymphocytic lesions associated with EBV represent a spectrum of reactive infiltrates to monoclonal populations.
