INTRODUCTIONPrimary tracheal tumors are rare. Commonly tracheal neoplasms are either squamous cell carcinoma or adenoid cystic carcinoma.1Tracheal Schwannoma are extremely rare and are more often found in the lungs and bronchi.2 Schwannoma’s are tumors that originate from tumorigenic Schwann cells attributed to loss-of-function mutations of NF type2 tumor suppressor gene.3 Standard treatment has not been established yet. Endoscopic resection has been widely used as a treatment modality but recurrence has always been a possibility. Previous literature has shown that optimal treatment is surgical resection and anastomosis of the involved trachea. Cases such as multiple tracheal schwannoma,4 transmural tracheal schwannoma,2,5 transmural schwannoma of trachea compressing the esophagus6 and plexiform schwannoma involving trachea and left recurrent laryngeal nerve7have been reported which were all treated by resection and anastomosis of involved trachea.We report a similar case of transmural tracheal schwannoma with extraluminal component of tumor extending into the left lobe of thyroid. Initially Nd:YAG laser ablation was performed to relieve the airway obstruction. Patient later underwent surgical resection with end to end anastomosis of trachea with en-bloc resection of left thyroid lobe. This case has been reported in line with the SCARE criteria.8KEY CLINICAL MESSAGE : Tracheal Schwannoma are rare neoplasms and can have spectrum of clinical presentation which causes diagnostic dilemma and delay in diagnosis. So far, tracheal resection and anastomosis has been the optimal management and follow up is essential.
