Intrapulmonary teratoma: an exceptional disease.

Intrathoracic teratomas almost always occur in the mediastinum, but occasionally, they may be found in the lung as intrapulmonary teratomas. Intrapulmonary teratomas have histologic findings that are similar to those of teratoma from other sites. Two successive patients with intrapulmonary teratomas presented to us in a variable manner. The clinical and radiologic features and the histopathologic findings are presented, and the relevant literature is discussed.
