title: Kaposiform hemangioendothelioma in adult. Report of a case with amianthoid-like fibrosis and angiectases.
abstract: A rare case of kaposiform hemangioendothelioma in adult is reported. The 11 x 7 x 5 cm tumor was excised from deep subcutis of the abdominal region in 37-year-old man. No signs of Kasabach-Merritt syndrome or lymphangiomatosis were present. Besides typical pattern of kaposiform hemangioendothelioma, following unusual features were found: dilated vessels producing a gross impression of spindle cell hemangioma, areas of amianthoid-like fibrosis, and diffuse immunoreactivity for CD99. The differential diagnosis included mainly spindle cell hemangioma (hemangioendothelioma), hemangiopericytoma-like solitary fibrous tumor, and Kaposi's sarcoma.
