Multifocal hemangioendotheliomas of bone mimicking metastases

Abstract

Hemangioendotheliomas are rare vascular tumors that can arise from soft tissue or bone. The former comprises hemangioma, epithelioidhemangioma, hemangiomatosis and massiveosteolysis or Gorham′s disease (which mimics malignantneoplasm due to aggressive osteolytic destruction). The rarer malignant counterparts are epithelioidhemangioendothelioma, hemangioendothelioma and angiosarcoma in increasing order of malignancy. The diagnosis of these lesions is difficult both clinically and radiologically. Hereby we report an unusual case which was mistaken for metastasis and was diagnosed with the help of histopathology.
