The use of monoclonal antibodies on paraffin sections in the diagnosis of cutaneous lymphoproliferative disorders.

Immunohistochemistry provides a new powerful tool for the diagnosis and classification of cutaneous lymphoid infiltrates. The use of a panel of monoclonal and polyclonal antibodies on routinely-fixed, paraffin-embedded tissue sections allows the correct classification of most cutaneous T-cell and B-cell lymphomas and of specific cutaneous manifestations of Hodgkin's disease and of "true" histiocytic lymphoma.
