T lymphocytes and mononuclear phagocytes in the skin infiltrate of systemic and discoid lupus erythematosus and Jessner's lymphocytic infiltrate.

T Lymphocytes and mononuclear phagocytes were measured quantitatively with the histochemical acid alpha-naphthyl acetate esterase (ANAE) method from paraffin sections of skin affected by systemic and discoid lupus erythematosus and by Jessner's lymphocytic infiltrate. The composition of the patchy cutaneous mononuclear cell infiltrates was similar in these three disorders.
