D2-40 is a commercially available monoclonal antibody directed against human podoplanin, a transmembrane mucoprotein that is expressed in lymphatic endothelial cells. Since its introduction, D2-40 immunoexpression has been described in a variety of lymphovascular neoplasms including lymphangioma, Kaposi sarcoma, and hemangioendothelioma, as well as nonvascular neoplasms such as epithelioid mesothelioma, seminoma, and hemangioblastoma. More recently, D2-40 immunoexpression has been reported in primary adrenal cortical tumors, schwannomas, and adnexal tumors of the skin. This brief review provides an update on the ever-expanding proposed applications of D2-40 immunohistochemistry in surgical pathology.
