Primary benign intratracheal schwannoma: A case report and review of the literature.

Shwannomas are rare benign tumours especially in tracheal. A 16-year-old male presented with a chronic cough, and a thoracic CT scan revealed a pedunculated tumour measuring approximately 11 × 13 mm in size, located 22 mm away from the main carina. Tissue sample was obtained via rigid bronchoscopy and cryobiopsy, and the pathological analysis confirmed the diagnosis of a benign nerve sheath tumour consistent with schwannoma. The patient subsequently underwent resection of the tumour and tracheal anastomosis. Schwannomas are uncommon pulmonary tumours that typically occur in adults, with a higher incidence among females. The presenting symptoms vary depending on the size and location of the tumour. Treatment options include therapeutic bronchoscopy or surgical resection, with the choice of approach based on tumour characteristics (pedunculated or sessile), preoperative surgical risk, and risk of recurrence. The prognosis is generally favourable, with a low risk of recurrence and excellent outcomes.
