Granuloma annulare is a lymphohistiocytic process of unknown cause characterized by necrobiotic dermal papules. Acetone-fixed frozen sections of eight granuloma annulare lesions were studied for the presence of T-cell subsets, using monoclonal antibodies to T-cell surface antigens. The palisading
We reviewed and reclassified the histology in 207 cases of granuloma annulare from our files. The most common pattern found was mononuclear infiltrative type (72%) in contrast to the palisading group (25%) and the epithelioid nodules (3%). Indeed, and entire spectrum from mononuclear infiltrates to
A mouse monoclonal antibody (HC1/1) specific for a differentiation marker of human monocytes and granulocytes has been generated by using as immunogen the monocytic cell line U937 differentiated with phorbol esters. This differentiation antigen has been characterized as the p150/95 member of the
