“…In our case, we diagnosed esophageal gastrointestinal stromal tumor for the reason of esophageal submucosal tumor with FDG accumulation. Meanwhile, some esophageal schwannomas with FDG accumulation are reported [ 10 – 12 ]. Schwannomas originate from nerve cells that express glucose transporter type 3, and FDG uptake is considered to be increased for this reason [ 13 ].…”

Lobulated esophageal schwannoma resected with concurrent approach from the thorax and cervix

BackgroundEsophageal schwannomas are rare esophageal submucosal tumors. We herein report a case of a lobulated esophageal schwannoma resected with concurrent approach from the thorax and cervix.Case presentationA 74-year-old woman visited our hospital with complaint of loss of consciousness, and a lobulated mediastinal tumor was discovered by chance in computed tomography. Upper gastrointestinal endoscopy showed a smooth elevated lesion at a position of 23–28 cm from the incisor teeth. A hypermetabolic appearance was noted on positron emission tomography. Based on these data, a gastrointestinal stromal tumor was suspected. The tumor was enucleated at the thoracic cavity while being pushed from the cervical incision. Pathological examination showed an esophageal schwannoma.ConclusionsWe experienced a case of lobulated esophageal schwannoma with fluorodeoxyglucose accumulation. We resected the tumor with concurrent approach from the thorax and cervix.

“…More recently, enucleation of esophageal tumors using minimally invasive thoracoscopic, laparoscopic and endoscopic techniques has been shown to be superior to open techniques in terms of reducing postoperative hospital stay, with no difference in operative time, intraoperative complications, or recurrence [2]. 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].…”

“…To the best of our knowledge, there were no reported cases treated by a transabdominal laparoscopic approach. Only two of the reported cases were of esophageal schwannomas in the lower esophagus and both were enucleated with thoracotomy approaches (Table 1) [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Laparoscopic Enucleation of Schwannoma Masquerading as a Leiomyoma

2017

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.

“…However, in certain cases, such as in one of our patients, VATS may not provide exposure that is adequate for tumor access. In very large submucosal tumors, VATS may lead to an increased risk of mucosal injury during extensive submucosal dissection [ 24 ].…”

Benign esophageal schwannoma: a brief overview and our experience with this rare tumor

et al. 2017

View full text Add to dashboard Cite

BackgroundBenign esophageal tumors are uncommon, comprising approximately 2% of esophageal tumors. Esophageal schwannomas constitute an even rarer entity, with few cases reported in the literature.Case presentationWe present a 66-year-old male who was referred for dysphagia. A computed tomography scan showed a well-demarcated, enhancing, and homogenous esophageal tumor measuring 50 mm. The tumor was hypermetabolic on positron emission tomography, and an endoscopic ultrasound-guided fine needle aspiration demonstrated the presence of benign spindle cells. We performed an uncomplicated, simple, tumor enucleation through a cervical approach. Histology revealed spindle-shaped cells in a fasciculated, disarrayed pattern. Immunohistochemistry demonstrated positive staining for S-100 protein and negative staining for KIT, CD34, desmin, and α-smooth muscle actin. These findings were consistent with a benign esophageal schwannoma.ConclusionsWe report our experience with esophageal schwannoma, a rare but benign diagnosis of the esophagus.
