[A case of natural killer T-cell lymphoma in the nasal cavity].
CD56 positive natural killer T cell lymphoma is characterized by destructive lesions in the nasal cavity and nasopharynx. Severe tissue necrosis makes histopathologic diagnosis difficult, generally necessitating multiple biopsies. A thirty-three-year-old male patient presented with complaints of nasal obstruction, hemorrhagic discharge of fetid odor, and rhinolalia. Immunohistochemical studies on biopsy specimens obtained from the lesion in the nasal septum and posterior nasal cavity revealed CD56 positive natural killer T cell lymphoma. The patient was treated with eight courses of combination chemotherapy, since then he has been in remission for more than 1.5 years.
