The recognition of mucosal-associated lymphoid tissue as a distinct entity has lead to the separate classification of tumors arising in this tissue, ie, the mucosal-associated lymphoid tissue lymphoma. Five patients with mucosal-associated lymphoid tissue lymphoma of the conjunctiva are described herein; four of the five patients had bilateral tumors. Laboratory analysis was done using microscopy, immunophenotyping, gene rearrangement analysis using both Southern blot and polymerase chain reaction techniques, and oncogene (bcl-1, bcl-2, and c-myc) rearrangment studies. Typical mucosal-associated lymphoid tissue lymphoma features were seen in all patients; three of four patients who underwent testing with immunphenotyping had light-chain restriction, four of five patients had a clone detected using Southern blot analysis, and all five patients showed clones on polymerase chain reaction analysis. No patient demonstrated oncogene rearrangement. In all patients, complete physical examinations and laboratory tests did not detect any evidence of systemic spread. After treatment, no evidence of local recurrence or dissemination was found during follow-up ranging from 2 to 3 years.
