ABSTRACT
NK/T-cell lymphoma is a severe and rare disorder in Africa and in Europe. Treatment is based on radiotherapy and chemotherapy. We here report two cases of elderly patients aged 55 years and 52 years, respectively, with bilateral nasal obstruction associated with purulent rhinorrhea. Clinical examination showed cleft palate. Diagnosis was made on the basis of immunohistochemical examination of biopsies. Both patients underwent CHOEP chemotherapy followed by radiotherapy. Nasal NK/T-cell lymphoma is an aggressive type of non-Hodgkin's lymphoma with specific clinicopathologic features. Combining chemotherapy with radiotherapy in patients with advanced stage of the disease does not seem to improve survival compared with radiotherapy alone, which is the treatment of choice especially for localized stages. Nasal NK/T-cell lymphoma is rare. Diagnosis is based on immunohistochemical examination. Treatment includes chemotherapy and radiotherapy. This lymphoma has a poor overall prognosis, even with appropriate therapy.
