This report describes the in situ demonstration of "T" lymphocytes and "T" lymphocyte subsets in tissue sections using a case of lichen planus as a model. The technique utilized is the indirect immunoperoxidase method with monoclonal antibodies to "T" cells and "T" cell subsets. In the case examined a predominance of helper "T" cells was found. The potential application of this method in the immunopathology of skin and internal organs is discussed.
