“…In our case, due to lack of definitive preoperative diagnosis of schwannoma, very large size, involvement of the mucosa which bled during endoscopy and presence of mild dysplasia, a segmental esophagectomy was done and a two stage procedure was preferred 8,9 . This can be done by thoracotomy or video-thoracoscopy.…”

“…Treatments included four enucleations, one partial resection and one subtotal esophagectomy. The common factor leading to esophagectomies was possibility for malignancy, [13][14][15] Preoperative diagnosis of schwannoma was regarded to be difficult, 4) so many cases needed surgical resection to diagnose. In some reported cases, although a benign schwannoma was diagnosed before surgery, subtotal esophagectomy was performed, because the tumor size was too large to repair without stenosis after partial resection.…”

IntroductionSchwannoma of the esophagus is rare and most frequently located in the upper thoracic esophagus. 1) Dyspnea frequently occurs and reports about it are recently increasing. [2][3][4][5][6] However, esophageal obstruction has not been previously reported, nor has acute surgical intervention been needed. We describe a case of a major schwannoma of the esophagus, which required emergency esophagectomy, and review 5 publications about tracheal compression. Case ReportA 59-year-old woman presented with a history of diabetes mellitus. She had been aware of dysphagia in the past 1 year. However, since this symptom seemed mild, she rejected further evaluation. She was transported to emergency room of another hospital after an emergency medical services (EMS) call, resulting from dyspnea and disturbed consciousness. Her condition required emergency intubation, which did not significantly improve her state. Laboratory data from arterial blood showed respiratory acidosis with hypoxemia and hypercapnia (pH 7.165, PaO2 79.8 mmHg and PaCO2 99.5 mmHg at bilateral positive airway pressure [BIPAP], FiO2 0.8, positive endexpiratory pressure [PEEP] 8 cmH2O, f 15). Hyperglycemia was also found. A computed tomography (CT) scan revealed a posterior mediastinal mass, about 10 cm in diameter. The tumor showed a heterogeneous pattern and strongly compressed the esophagus and trachea (Fig. 1a, b). The tracheal lumen narrowed to 9 × 4 mm at the minimum point. The CT scan also showed the pneumonia in the left lower lung lobe. The patient was then taken and A Case of Benign Esophageal Schwannoma Causing Life-threatening Tracheal ObstructionAyako Tomono, MD, 1 Tetsu Nakamura, MD, PhD, 1 Yasunori Otowa, MD, 1 Tatsuya Imanishi, MD, PhD, 1 Yugo Tanaka, MD, PhD, 2 Yoshimasa Maniwa, MD, PhD, 2 and Yoshihiro Kakeji, MD, PhD 1A 59-year-old woman presented with a 1-year history of dysphagia. She suffered from a large mediastinal mass obstructing trachea and bilateral main bronchus, which led to dyspnea and disturbed consciousness. Immediate intubation and surgery was required. A solid tumor that included esophagus and right vagal nerve, and adhered to the membranous part of the bronchus was found. However, the tumor could be resected en bloc and the patient has been free from recurrence. Pathologically, the tumor exhibited proliferative spindle cells and was diffusely positive for S-100 protein. It was therefore diagnosed as a benign esophageal schwannoma. To our knowledge, this is the first report of tracheal obstruction from a benign esophageal schwannoma, which we successfully treated with emergency subtotal esophagectomy.
