Anterior Chest Wall Mass in an Asymptomatic Child

We describe a pediatric case of mediastinal benign teratoma presenting as recurrent chest wall mass. Most common differential diagnosis for chest wall mass in children is cavernous hemangioma, PNET/ Ewing’s sarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma.These tumors arise from chest wall and may have both intra and extra-thoracic components.The treatment of choice for benign mediastinal teratomas in children <15 years is total surgical excision  and there is no role of radiotherapy.  Recurrence of these tumors has not been reported after complete resection; therefore, long term prognosis is excellent.
