Abstract:
Temporal bone lymphomas are rare and typically metastatic neoplasms. We describe a case of primary B cell lymphoma that originated in the external auditory canal of an elderly woman. The diagnosis was based on histopathologic examination supplemented by immunophenotypic analysis. The patient was treated with external-beam radiation and remained disease-free throughout 9 years of follow-up. We also point out that the presence of non-Hodgkin's lymphoma in an unusual site may be an indication that the patient has an acquired immunodeficiency syndrome.
