E-cadherin, a member of the cadherin family of transmembrane adhesion receptors, is critical for cutaneous barrier function, as it promotes keratinocyte and Langerhans cell adhesion in the epidermis. Recent murine models of chronic inflammation identified new E-cadherin expressing subsets of mononuclear phagocytes, including alternatively activated macrophages and selected inflammatory dendritic cells. It has been shown in vitro that expression of E-cadherin by murine macrophages promotes their homotypic aggregation and fusion to multinucleated giant cells (MNGCs), a signature cell type of granulomatous inflammation. The purpose of this study was to assess E-cadherin expression on histiocytes and giant cells in cutaneous granulomas in humans. E-cadherin expression was evaluated by immunohistochemistry of formalin-fixed paraffin-embedded skin biopsies of foreign body granulomas (n = 21) and sarcoidosis (n = 21). The results showed consistent membranous E-cadherin staining pattern on mononucleated histiocytes and MNGCs in both granuloma types. These E-cadherin expressing histiocytes are distinct from dermal Langerhans cells because they lacked CD1a expression. Our findings suggest that E-cadherin expressing mononuclear histiocytes are likely precursors for MNGCs in cutaneous granulomas and may play a critical role in disease pathogenesis.

D015726 Giant Cells Multinucleated masses produced by the fusion of many cells; often associated with viral infections. In AIDS, they are induced when the envelope glycoprotein of the HIV virus binds to the CD4 antigen of uninfected neighboring T4 cells. The resulting syncytium leads to cell death and thus may account for the cytopathic effect of the virus.
