title: Angiocentric T-cell lymphoma of the nose, paranasal sinuses and hard palate.
abstract: Sixty-five cases of malignant lymphoma of the nose, paranasal sinuses and hard palate were retrospectively analysed to identify the presence or absence of angiocentric lesions. We observed that the 23 patients with angiocentric lesions had a worse prognosis with a shorter duration of response and also a shorter duration of survival, compared with 42 cases of malignant lymphoma of the same anatomical region but without angiocentric lesions. Patients with angiocentric lymphoma were associated with other bad prognostic factors such as elevated levels of lactic dehydrogenase and beta 2 microglobulin, local bone destruction and lymphopenia. Immunophenotyping studies showed that most patients with angiocentric lesions had T cell lymphomas (18 of 23, 78 per cent). We believe that patients with angiocentric T cell lymphomas of the nose, paranasal sinuses and hard palate represent a distinctive clinico-pathological entity with different clinical presentation and outcome. Patients with angiocentric T cell lymphomas had frequent relapse at extranodal sites and combined therapy should be considered as the initial therapeutic approach.
