title: [T lymphoma of the nasopharynx, a rare entity. Apropos of a case].
abstract: We report one case of nasal T-cell lymphoma (NTL) that we studied histologically and with a panel of monoclonal antibodies. It is a rare etiology of the so-called lethal midline granuloma. The diagnosis of NTL if often difficult because of spreading necrosis, cellular polymorphism and necessity of getting frozen snap sections for immunohistochemical techniques. We describe histological, immunohistochemical features of NTL and its usual follow up. Then we compare them with those of malignant lymphomas of the Waldeyer's ring which are very different although they are located very near to NTL. These differences raise the hypothesis of a possible role of the local environment.
