Polypoid nasal pseudolymphoma.
An unusual polypoid lesion of the nasal cavity in a 48-year-old woman with chronic obstruction consisted of aggregated nodules of benign lymphoid tissue with germinal center formation. She had no lymphadenopathy or other evidence of a systemic lymphoid disorder. To the authors' knowledge, this nonneoplastic lymphocytic proliferation, analogous to so-called "pseudolymphoma" at other sites, has not been reported heretofore in the nasal cavity or paranasal sinuses.
