  abstract = {Background: Schwannomas are benign mesenchymal tumor originated in the Schwan cells of peripheral, spinal, or cranial nerve sheaths. They represent approximately 0.2-2% of benign tumors in the tracheobronchial tree. To date, only sporadic case reports exist in western literature. Case presentation: We present a 35-year-old female, whose initial complaints were dyspnea, persistent cough, and chest pain for two months. In a chest CT-scan, a solid tumor was identified in the juncture of the right main bronchus and the emergence of the ipsilateral superior bronchus. Said tumor had both an intra and extra-luminal component, and its dimensions where 2.9×2.6×2.7cm. Results: A right posterolateral thoracotomy was performed with selective intubation. The possibility of preserving the right upper lobe was identified transoperatively, with the right upper bronchus being sutured to the right main bronchus, without complications. The histopathologic report was of a benign bronchial Schwannoma, with the formation of Verocay bodies in the HE stain, and intense positivity for the S100 protein in the subepithelial lesion. Patient follow-up was performed with a new CT-scan and flexible bronchoscopy 3 months after surgery, with no evidence of recurrence. 23 cases of endobronchial Schwannoma reported in the available literature were subsequently analyzed, with emphasis on clinical presentation, treatment offered and follow-up. Conclusions: Endobronchial Schwannomas are an uncommon type of airway tumor, and are rarely thought of as an initial diagnosis. Total resection of the tumor is of upmost importance to avoid recurrence. Surgical resections should be considered in all patients with high probability of residual tumor through endoscopic resection, most notably those with a known or suspected extraluminal component. More case reports are needed to develop a better understanding of the best diagnostic, treatment, and follow-up options.},
