Abstract
|
|
|
|
Hemangioendothelioma (HE) is a group of vascular neoplasms that may be considered benign or malignant in their activity. HE is differentiated by both its characteristic behavior and histologic appearance into benign (hemangioma) and malignant tumor (angiosarcoma). The tumor is characterized by neoplastic proliferation of epitheloid or histiocytic endothelial cells, and it commonly occurs in the soft tissues of extremities and liver, lung, but rarely in the external auditory canal. Surgical excision is the treatment of choice and the prognosis is generally good. The authors report, along with a review of related literatures, a 66 year-old male patient with HE of the right external auditory canal.
