Abstract

The monocyte/histiocytic response in granuloma annulare has not been extensively studied. We studied the immunohistochemical staining pattern in granuloma annulare by using a panel of markers for “histiocytic” cells including Ham 56, KP1, factor XIIIa, Mac 387, vimentin, and lysozyme. The infiltrate failed to stain with the histiocytic markers, except with antibodies against vimentin and lysozyme. Commonly used histiocytic markers for infectious, immunogenic, and foreign body granulomas fail to stain the infiltrate in granuloma annulare. We hypothesize that a locally derived, immunologically distinct population of histiocytes produces the reaction pattern of granuloma annulare.
