NK/T lymphoma is a rare type of non-Hodgkin's lymphoma. It corresponds to a clinical entity with necrosis that starts preferentially in the nasal cavities and the nasopharynx and extends to the centrofacial bone structures. Its anatomopathological diagnosis is not always obvious. Modern immunophenotyping and molecular biology tools have made it possible to isolate this type of lymphoma. Treatment is based on radiotherapy and chemotherapy. Nasosinus localization of T/NK lymphoma is rare. This is the case report of a 18-year-old female patient who presented with nasal obstruction and foul smelling, edema of the right hemiface and an ulcerative lesion over the palate of 4 months duration, which had been treated with antibiotics without success. After performing a number of diagnostic tests, it was found histologically and confirmed by immunohistochemical analysis that the patient had an ENKL, nasal type (also known as angiocentric T-cell lymphoma). Our Purpose of the presentation is To discuss the particularity of this localization, the diagnosis difficulties and therapeutic modalities.
