Abstract
Recent investigations have demonstrated the utility of the monoclonal antibody D2-40 as a marker for lymphatic endothelium. D2-40 can be used on formalin-fixed and paraffin-embedded materials. Our objective was to elucidate, using D2-40 immunohistochemistry, the differences among capillary hemangiomas, and especially between kaposiform hemangioendothelioma (KHE) and tufted angioma (TA). We studied four cases of KHE, nine cases of TA, and 31 cases of other vascular tumors. Antibodies against CD31, CD34, factor VIII-related antigen, and GLUT1 were also applied.
