Composite cutaneous hemangioendothelioma on the back.

Composite cutaneous hemangioendothelioma (HE) is the most recently described variant of the lesions known as HEs. It is characterized by a mixture of histologic patterns, namely, epithelioid HE, retiform HE, and spindle cell hemangioma. We report a new case of this rare tumor located on the back of a 23-year-old woman. This neoplasm is considered to be of borderline or low-grade malignancy, because despite its frequency it rarely metastasizes.
