“…Esophageal schwannomas are exceedingly rare with only a handful of cases reported in the literature [3]. A literature review performed for the past decade, 2005 -2015, revealed a total of 21 cases of which two cases were of concurrent esophageal schwannomas [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The surgical approaches to these include four thoracoscopic, six thoracotomy, five cervical approaches, and five esophagectomies or partial esophagectomies.…”

Laparoscopic Enucleation of Schwannoma Masquerading as a Leiomyoma

We present a case, literature review, and video of a transabdominal laparoscopic enucleation of an esophageal schwannoma. A 53-yearold female with dysphagia was found to have a 23 × 27 mm mass in the lower esophagus, which was initially diagnosed as a leiomyoma on endoscopic ultrasound without biopsy. At the time of her laparoscopic enucleation 12 months later, the lesion had grown to 60 × 55 × 30 mm and was excised with a full-thickness segment of the esophageal wall, with closure of the resulting defect over a bougie. Postoperatively, the patient's recovery was complicated by an esophageal leak which was successfully managed with endoscopic drainage. Esophageal schwannomas are rare esophageal lesions that have historically been treated with esophagectomy. Thoracoscopic or laparoscopic enucleations of smaller lesions have been more recently reported but larger lesions have usually required open surgery. Internally placed endoscopic drains have previously been shown to be a valid alternative to external drainage in patients with contained collections after resection surgery. They have the advantage of allowing patients to continue oral fluids during the recovery phase rather than relying on enteral or parenteral feeding. We propose that laparoscopic transabdominal enucleation of esophageal schwannoma with closure of the resulting full-thickness defect be considered as an organ and function sparing alternative for the management of large lower esophageal schwannomas. We further propose that contained leaks resulting from esophageal operations can successfully be managed with internal endoscopic drainage.

“…Symptoms of this tumor include dysphagia, dyspnea [ 1 , 3 ], chest pain, and hematemesis, and appear when the tumor increases in size. Imaging studies (positron emission tomography, computed tomography, and magnetic resonance imaging) are useful for the confirmation of esophageal tumor [ 1 , 4 , 5 ]. Endoscopic ultrasonography-guided fine needle aspiration biopsy is not always useful for diagnosis, as in our cases [ 1 ].…”

Schwannomas of the esophagus are rare peripheral nerve tumors. A 37-year-old woman with dysphagia was found to have an intramural tumor of the upper esophagus. The lesion was revealed on computed tomography. Endoscopic ultrasound biopsy was nondiagnostic. Through right thoracotomy, the mass was enucleated from the wall of the esophagus. Benign schwannoma was diagnosed only after immunological staining examination.

“…Symptoms of this disease include dysphagia, dyspnea, and chest pain, and are likely to appear and worsen as the schwannoma increases in size [6]. Fluorodeoxyglucose positron emission tomography as well as CT and MRI are reportedly useful for the confirmation of mediastinal tumors [7].…”

Esophageal schwannoma: a case report

et al. 2013

Most tumorous lesions of the esophagus are esophageal cancers. Benign primary tumors of the esophagus are uncommon, and account for approximately 2% of all esophageal tumors. More than 80% of benign esophageal tumors are leiomyomas, with schwannomas being rare. A 55-year-old woman visited our internal medicine department with complaints of palpitations and discomfort during swallowing. A chest computed tomography scan showed a lobulated tumor (75 × 57 × 80 mm) in the upper to middle mediastinum, with homogenous inner opacity, compressing the esophagus. Upper gastrointestinal endoscopy revealed a smooth-surfaced elevated lesion covered with normal mucosa, and a schwannoma was diagnosed based on the biopsy result. The tumor was large. It was thus considered to be difficult to repair the esophagus by direct anastomosis after tumor resection. Therefore, subtotal esophagectomy and esophagogastrostomy in the right thorax were performed. Histopathological examination revealed spindle-shaped cells in a fasciculated and disarrayed architecture and nuclei in a palisading pattern. Immunohistochemical studies revealed S100 protein positivity and the absence of staining for α smooth muscle actin (αSMA), CD34 and CD117, thereby establishing the diagnosis of benign schwannoma. Her postoperative course was uneventful and there has been no evidence of recurrence to date.
