Giant thymic Hyperplasia is a rare lesion in children. We report a case of giant thymic hyperplasia in the right anterior mediastinum in a 2 year-old male patient. Presenting symptom was frequent cough and sputum, plain chest X-ray and computed tomography showed huge mass in the right anterior mediastinum. The tumor resection was done through a median sternotomy for the prevention of progression to atelectasis caused by mass effect and tissue diagnosis. An open biopsy specimen showed normal thymic architecture. The patient recovered without any problem and is doing well untill now. We report this rare case of giant thymic hyperplasia with review of the literature.
