title: Epithelioid hemangioendothelioma of nasal cavity.
abstract: We present a rare case of epithelioid hemangioendothelioma (EHE) in the nasal cavity of a 40-year-old Indian male who presented with history of intermittent epistaxis. The lesion was tested for a panel of immunohistochemical markers like vimentin, CD31, CD34, Factor VIII, vascular endothelial growth factor (VEGF) and Ki67. Immunohistochemically, the neoplasm showed striking positivity for vimentin, CD31, CD34 and weak positivity for VEGF; positivity was also noted for Factor VIII especially in the miniature intracytoplasmic vascular lumina.
