Fibrobronchoscopic evidence of endobronchial hairs in intrapulmonary teratoma with hemoptysis but without trichoptysis.

Intrapulmonary teratoma (IPT) is exceedingly rare, hence preoperative diagnose is usually inaccurate. A 21-year-old man was presented with a 5-year history of recurrent hemoptysis and left upper lung mass with heterogeneous opacity on chest x-ray. Diagnostic fibrobronchoscopy detected tuft of brownish hairs in the left upper anterior segmental bronchus, achieving the diagnosis of IPT preoperatively, which was further confirmed by lobectomy. The case report is noteworthy with fibrobronchoscopic finding of endobronchial hairs in a heterogeneous lesion, which underscores the important role of fibrobronchoscopy in the differential diagnoses of chronic cavitary lesions such as IPT without trichoptysis.
