title: T-cell lymphoma occurring in the oropharynx.
abstract: Two cases of documented T-cell lymphoma occurring in the oropharynx are described. Both patients presented with cervical lymphadenopathy and involvement of oropharyngeal tissues. Although classification of these patients' lesions in relation to other known T-cell lymphomas was difficult, the location of the lesions in both cases and certain morphologic features in one case at least suggested that the malignant cells may have arisen from peripheral T-lymphocytes. In both patients, the neoplastic cells showed a tendency to impinge upon the oral epithelium, in keeping with the pattern of involvement of epithelial tissues seen in several varieties of T-cell lymphoproliferative disorders. The possibility that these oropharyngeal T-cell lymphomas may represent a distinct type of T-cell neoplasm is raised.
