The desmoid tumor was totally removed except for the small part where the desmoid tumor had invaded into the chest wall at the apex. No chemotherapy and radiotherapy were done after operation. One month later, the desmoid tumor recurred from the apex of the right thorax into the thoracic cavity. Fortunately the patient has no respiratorysymptom until now. The authers discuss the origin of the desmoid tumor and the strategy against the recurrent desmoid tumor in children.
