“…Esophageal schwannoma is rare, with only 19 reported cases. [1][2][3][4][5] Schwannomas tend to arise during the fourth to fifth decades of life and are more common in women and in blacks. [1][2][3] These tumors have been classified as a subset of gastrointestinal stromal tumors.…”

“…[1][2][3][4][5] Schwannomas tend to arise during the fourth to fifth decades of life and are more common in women and in blacks. [1][2][3] These tumors have been classified as a subset of gastrointestinal stromal tumors. 6 Most gastrointestinal schwannomas appear in the gastric or intestinal mucosa, and their origin is thought to be the submucosal supporting cells or the Schwann cells within the myenteric plexus.…”

“…Histologically, the diagnosis of schwannoma is confirmed by the presence of S-100 immunoreactivity and the absence of histologic markers of smooth muscle, such as desmin. [1][2][3] Malignant transformation of gastrointestinal schwannomas is extremely rare, and conservative management has thus been advocated. Lymphatic or distant spread of disease is also rare, and negative surgical margins are the only current therapeutic recommendations.…”

Background. Isolated defects in the cervical esophagus in patients who have not undergone total laryngectomy are uncommon. We report 2 cases of rare esophageal tumors requiring reconstruction of the cervical esophagus after tumor resection.Methods and Results. The patients were a 51-year-old woman with an esophageal granular cell tumor and a 54-yearold woman with an esophageal schwannoma. Both defects were reconstructed with a radial forearm flap. A small subclinical leak developed in 1 patient and healed spontaneously within 2 weeks. At 1 year and 2 years of follow-up, both patients were consuming a normal diet and had normal voices.Conclusions. A thin and well-vascularized flap such as the radial forearm flap is essential for reconstructing an isolated cervical esophageal defect so as to maximize functional outcome. Keywords: cervical esophagus; esophageal reconstruction; granular cell tumor of the esophagus; schwannoma of the esophagus; radial forearm flap Schwannomas and granular cell tumors rarely arise in the esophagus. They usually do not cause clinical symptoms that prompt medical intervention. In many cases, such tumors can be enucleated without the need for esophageal resection. There have been no reports in the literature of reconstruction of the cervical esophagus with free tissue transfers after resection of esophageal schwannomas or granular cell tumors. Reconstruction of the esophagus in patients with an intact larynx and trachea is technically more difficult because of limited exposure. We present 2 cases of rare, symptomatic cervical esophageal tumors that required free flap reconstruction to restore esophageal integrity.CASE REPORTS Case 1. The patient was a 51-year-old woman who initially presented with a history of dysphagia that had lasted several months. Further workup revealed a hyperfunctioning thyroid nodule that was removed in a right thyroid lobectomy. The procedure was uncomplicated, and pathologic examination revealed a benign thyroid adenoma. The patient recovered well postoperatively but returned 1 year later with progressively worsening dysphagia Correspondence to: P. Yu

“…Conversely, myogenic tumors are frequently found in the esophagus, where neurogenic tumors are extremely rare. Only 24 reports in the literature have described esophageal schwannoma, according to our research of PubMed as of December 2003 [3][4][5][6][7][8][9][10][11][12].…”

Esophageal schwannoma treated by transthoracic esophagectomy: a case report

We report the case of a 72-year-old man with esophageal schwannoma who underwent the Ivor Lewis procedure. He suffered from dysphagia for 6 months. Esophagoscopy revealed a submucosal tumor bulging on the posterior wall 30 cm distant from the incisors. Endoscopic ultrasonography (EUS) revealed tumor located within the muscularis propria, the fourth layer of the esophageal wall. Upper gastrointestinal series showed an elevated lesion, 6 cm in diameter, on the posterior wall of the upper thoracic esophagus. These findings were suggestive of leiomyosarcoma. The area of esophagus including the tumor was resected using the Ivor Lewis procedure. The tumor was 5.5 ϫ 4.5 ϫ 4.5 cm in size, with a smooth surface that was elastic and firm. Histological examination revealed spindle-shaped cells with oval nuclei, and Antoni A and B types coexisted in the tumor tissue. Immunohistochemical studies yielded positive results for S-100 protein and negative results for CD34, desmin, and α-smooth muscle actin. A diagnosis of esophageal schwannoma was established. He was discharged from the hospital and has been doing well with no recurrence for 20 months after surgery.
