Immunohistological Study of Non-Hodgkin's Lymphoma in the Head and Neck

Abstract

We retrospectively analyzed 52 patients to investigate pathological and immunohistological classification of non-Hodgkin's lymphoma in the head and neck and their clinical features were reviewed.
Diffuse large cell lymphomas were common in patients with Waldeyer's ring involvement.
All Waldeyer's ring lymphomas were found to express B-cell phenotype. Nodal and sinonasal lymphomas expressed T-cell phenotype in many patients.
Prognosis of sinonasal lymphoma was poor irrespective of T-cell or B-cell type.
It was important to choose chemotherapy based on histological type.
