Surgical treatment of a case with rapidly growing mass lesion after trauma: on the left forearm arteriovenous malformation.

In this case, we report a vascular malformation with high flow pattern complicated with trauma. A postoperative histopathology examination confirmed an arterio-venous malformation in specimens of surgical excision material. In our opinion, posttraumatic progression of a vascular malformation is an emergency and requires an urgent evaluation with surgery at any localization of the body.
