T-cell origin of Lennert's lymphoma. Immunohistochemical and immunologic study of one case.
We observed a patient with Lennert's lymphoma. Immunocytochemical study of paraffin sections by the immunoperoxidase technique and immunologic study of viable cell suspension by monoclonal antibodies confirmed the T-cell nature of the neoplastic lymphoid cells. Subtyping showed a predominance of helper T lymphocytes. The histiocytic nature of the epithelioid-cell component of Lennert's lymphoma was also shown by immunostaining.
