Histopathology of patients with angiosarcoma in the setting of solid organ transplant. A) CM angiosarcoma 200x: Needle core biopsy of the liver showing inter-anastomosing channels with papillary formation lined by atypical endothelial cells typical of angiosarcoma (200X). B) CM angiosarcoma 400X CD31: Immunohistochemical stain against CD31(endothelial marker) demonstrates with brown staining the neoplastic endothelial cells of this angiosarcoma (400X). C) KM angiosarcoma 200X: A high grade angiosarcoma composed of cellular spindle malignancy growing in fascicles with multiple mitotic figures with scattered red blood cells but without evidence of vascular formation (200X). D) KM CD31 400X: Immunohistochemical stain against CD31 (endothelial marker) demonstrates with brown staining the neoplastic endothelial cells of this high-grade angiosarcoma (400X).
