Laryngeal NK/T Cell Lymphoma, Nasal Type: Case Report and Literature Review

Abstract

Extranodal Natural Killer T-cell lymphoma, nasal type represent a rare and aggressive entity of the non-Hodgkin's lymphomas. Laryngeal localization is rare and has a poor prognosis. We report the case of a 66-year-old patient who consulted for dyspnea, dysphonia and dysphagia. Endoscopic examination revealed an endo-laryngeal lesion. Anatomopathological study with immunohistochemistry concluded to a peripheral T NK/T-cell lymphoma nasal type. The extension workup was without abnormalities. Induction chemotherapy without anthracyclines was administered followed by conformal radiotherapy with intensity modulation in arctotherapy. Significant advances have been made over the past decade including better clarification of clinical heterogeneity, more accurate classification using imaging modalities, establishment of new prognostic models, and sequential use of anthracycline-free radiotherapy and chemotherapy in early stages and risk-adapted first-line treatment strategies in advanced stages.
