Hemangioendothelioma of the Forehead – A Rare Case Report

Hemangioendothelioma is the term used to name those vascular neoplasms that show a borderline biological behavior, intermediate between entirely benign hemangiomas and highly malignant angiosarcomas. Although originally spindle cell hemangioendothelioma was proposed as a specific clinicopathologic variant of hemangioendothelioma, currently, it is considered as an entirely benign lesion, and thus, the name spindle cell hemangioma seems to be the most accurate for this lesion. Authentic hemangioendotheliomas involving the skin and soft tissues include Papillary intralymphatic angioendothelioma (also known as Dabska tumor), Retiform hemangioendothelioma, Kaposiform hemangioendothelioma, Epithelioid hemangioendothelioma, Pseudomyogenic hemangioendothelioma (also known as epithelioid sarcoma-like hemangioendothelioma), and Composite hemangioendothelioma. Each of these neoplasms exhibit characteristic histopathologic features.
