[Strictly epidermotropic "Ketron Goodman"-type lymphoma. Immunohistochemical and ultrastructural analysis of a case].
We report a case of T cell lymphoma which was exclusively located within the epidermis. The T cells of this lymphoma were all of suppressor-cytotoxic phenotype. They did not express the CD7 antigen and a molecular biology study showed T cell type genotypic rearrangements. Both immunohistochemical and ultrastructural studies showed close contacts between lymphoma and Langerhans cells.
