title: [A case of intrapulmonary teratoma presenting with expectoration of white hair and cheese-like material].
abstract: A 41-year-old man presented with expectoration of white hair and cheese-like material. The chest radiograph showed a round shadow adjacent to the right hilum. Bronchofiberscopy revealed strands of white hair and an obstruction consisting of sebaceous material in the right B3b bronchus. Right upper lobectomy was performed. Histological examination confirmed the diagnosis of intrapulmonary mature teratoma. This characteristic clinical presentation and the bronchofiberscopic findings may have been specific for the diagnosis of teratoma in this case.
