Lymphocytic infiltration of the skin (Jessner): a T-cell lymphoproliferative disease

Abstract

Recent studies have suggested that Jessner's lymphocytic infiltration of the skin and lymphocytoma cutis both represent pseudo‐B‐cell lymphomas. We have now done immunohistochemical studies on frozen skin sections of six patients with lymphocytic infiltration of the skin. In all cases a predominance of T lymphocytes was observed and B lymphocytes were sparse or completely absent. These results indicate that Jessner's lymphocytic infiltration of the skin is a T‐cell lymphoproliferative disease which, unlike lymphocytoma cutis, cannot be regarded as a pseudo‐B‐cell lymphoma.
