[Immunological characterization of malignant epidermotropic lymphoma cells in cutaneous infiltrates (author's transl)].

Immunological characterization of cells in the malignant epidermotropic lymphomas requires techniques which define the lymphocytic nature of the cells, and for the lymphocytes techniques which demonstrate subpopulations of T or B cells. The results obtained using such methods in patients with cutaneous lymphomas are reported. The predominantly thymodependent nature of the cells of epidermotropic lymphomas is confirmed and the existence of a thymodependent non-epidermotropic cutaneous lymphoma is demonstrated.
