The application of a monoclonal antibody to CD62L on paraffin‐embedded tissue samples in the assessment of the cutaneous T‐cell infiltrates

Abstract

CD62L can be successfully applied in formalin-fixed tissue and exhibits enhanced specificity compared to CD7 in the evaluation of cutaneous T-cell infiltrates. Both CD62L and CD7 in paraffin-embedded, formalin-fixed tissue are useful diagnostic adjuncts, especially in regard to the discrimination of lymphomatoid hypersensitivity reactions from true endogenous T-cell dyscrasia.
