Lymphoma of the nasal cavity and paranasal sinuses: A case series.

BackgroundLymphomas of the sinonasal tract are a rare and heterogeneous subset of solid sinonasal neoplasms.ObjectiveTo characterize, in this case series, presenting symptoms, treatment modalities, and outcomes for patients with sinonasal lymphoma within a single institution.MethodsRetrospective patient data were collected from an academic, oncologic center and entered into a repository designed to capture outcomes for sinonasal malignancies. Patient demographics, presenting symptoms, imaging findings, treatment modalities, and health status were retrospectively extrapolated and evaluated by using Kaplan-Meier estimations for survival probability.ResultsPatients with sinonasal lymphoma with a mean follow-up of 50 months were identified (n = 18). Histologic diagnosis included the following: diffuse large B-cell lymphoma (n = 9), natural killer/T-cell lymphoma (n = 5), follicular lymphoma (n = 1), T-cell lymphoma (n = 1), and lymphoma-not otherwise specified (n = 2). The most frequent presenting symptoms we...
