Thoracoscopic diagnosis of Goodpasture's syndrome.

Goodpasture's syndrome is a rare glomerulonephritis that is associated with or preceded by hemoptysis. An 11-year-old boy who demonstrated hematuria and hemosputum was successfully and definitely diagnosed as having Goodpasture's syndrome by thoracoscopic resection, although most cases generally require an open thoracotomy. The patient's postoperative course was uneventful. Thoracoscopy appears to be a safe and effective modality for the diagnosis of Goodpasture's syndrome.
