To the Editor Demirci et al1 reported the successful treatment of a primary B-cell mucosa-associated lymphoid tissue (MALT) lymphoma of the iris with rituximab. The diagnosis was based on fine-needle aspiration (FNA) cytology findings described as “a monomorphic population of small to medium-sized hyperchromatic, CD20+ lymphocytes.”1 A few reactive CD3+ reactive lymphocytes were also observed. The results of other immunohistochemical stains were not reported, nor were any adjunct studies such as flow cytometric immunophenotyping or polymerase chain reaction for IgH gene rearrangement obtained.
