Three cases of intrapulmonary teratoma are described. A specific symptom of trichoptysis
occurred in two patients. The other presented with only recurrent hemoptysis. All were treated
by lobectomy of the affected lung. Pathologic examination in each specimen showed that the
tumor had a cystic portion which was connected to the bronchial system and contained sebaceous
material and pieces of hair. The solid portion consisted of tissues representing all three germ
cell layers. The pathologic findings correlated well with the clinical symptoms and radiologic
findings in the patients.
