Abstract

Pulmonary schwannoma is a rare neoplasm that arises from peripheral nerve sheath, Schwann cells, in the lungs and mostly remains asymptomatic for months. This report presents a seven-year-old female patient with an occasional cough and fever. She was hospitalized due to the lack of response to outpatient treatments, including antibiotics and antifebrile. A biopsy was taken from the mass by bronchoscopy, and the pathology report indicated the presence of a low-grade spindle cell, Verocay body, and Antoni B areas. Based on the pathologic findings, immunohistochemical (IHC) analysis was requested. The results indicated diffusely positive for S-100 protein, and accordingly, the diagnosis of schwannoma was confirmed. Thoracotomy and lobectomy were performed. Tracheobronchial schwannoma can be treated with surgical resection or bronchoscopy. © 2020
