A 2-year-old patient with a history of non-Hodgkin’s lymphoma (NHL) was presented to our hospital with the complaint of shortness of breath and wheezing. Posteroanterior chest radiograph revealed hyperlucency and hyperexpansion of the right hemithorax. We performed computed tomography (CT) because of a suspicion of foreign body aspiration. CT revealed right main bronchus occlusion by a hypodense lesion. Bronchoscopy revealed a mass lesion in the right main bronchus which was histopathologically diagnosed as NHL. Only a few cases of endobronchial recurrence of lymphoma have been reported in the current literature, but there is no reported case in a pediatric patient.
