title: Lymphoid hyperplasia of larynx simulating neoplasia.
abstract: A rare case of lymphoid hyperplasia of the adult larynx (hyperplasia of the laryngeal tonsil) is reported. While this benign lesion recurred following surgical excision, the patient has been followed for more than two years without additional therapy and is asymptomatic. Seven additional cases of laryngeal lymphoid hyperplasia in the English literature are reviewed. The problems related to inadequate sampling (biopsy) and the histologic criteria for diagnosis are emphasized. To define the pathogenesis and ultimate biologic potential of this lesion, more cases must accrue and be studied with a long follow-up.
