  • Abstract
  • Look Inside

 Immunological, histopathological, and ultrastructural features of nasal T cell lymphoma was investigated in a patient whose initial diagnosis was "rhinitis gangrenosa progressiva" or lethal midline granuloma. Tumor cells showed positive staining with anti-Leu 1 monoclonal antibody which defined all peripheral T lymphocytes, and with anti-Leu 3a which defined helper/inducer T cell subset. In vitro assay of tumor cells cocultured with normal tonsillar lymphocytes, tumor cells strongly suppressed DNA synthesis of tonsillar lymphocytes. These results indicated that tumor cells might be originated from immunoregulatory inducer T cells. Histopathological and ultrastructural features of this case were compatible to those of T cell lymphoma previously reported.
