title: [Intrathoracic schwannoma].
abstract: The schwannoma (neurilemmoma) is a slow-growing benign tumor originating from Schwann sheath whose location in the chest cavity is exceptional. It is generally asymptomatic and is discovered incidentally but can cause symptoms when the lesion grows or invade underlying structures. Its importance lies in the possibility of confusion with malignant tumors. We present a patient who complains of chest pain caused by a prolonged course schwannoma. The tomographic image is suggestive of extrapulmonary tumor, so the schwannoma in this location should be considered in the differential diagnosis of metastatic or primary pleural tumors such as lipoma, solitary fibrous tumor and mesothelioma.
