Non-Hodgkin's lymphoma limited to the larynx

A case of primary laryngeal non-Hodgkin's lymphoma is detailed, with a review of the reports in the English literature on this rare site of presentation. Symptoms at onset generally include hoarseness, and may be observed up to 60 months prior to diagnosis. Four of the five cases classified by the Rappaport system are of diffuse histology. The histologic distinction of true lymphoma from pseudolymphoma, which may mimic lymphoma both grossly and microscopically, is reviewed. Local radiotherapy is a curative treatment of choice, with 16 of 18 cases disease-free throughout follow-up.
