[Thrombosed cavernous hemangioma of the anterior mediastinum. A report of one case].

Mediastinum hemangioma is a rare benign tumor. We performed surgery and present the first reported case in Chile. The patient is a 24-year-old symptomatic woman, referred to our hospital from a rural health center. The patient had all routine preoperative studies, chest radiographs and computed tomography of the thorax. We performed a median sternotomy with a complete resection of the mass. During the 36-month follow-up, she was well, asymptomatic and without relapse evidence. A review of the most outstanding characteristics of this rare tumor is presented.
