“…Despite the existence of advanced imaging modalities, such as ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI), only a few cases of RSs are diagnosed prior to resection ( 9 ). Diagnosis is usually made following excision and histological examination ( 10 ). Surgery is the primary treatment choice for RS; however, in malignant RS, a poor prognosis, such as neurofibromatosis type 1 (von Recklinghausen's disease), which is characterized by the occurrence of visceral neoplasms along with abnormal and numerous skin diseases ( 11 , 12 ), may occur ( 4 ).…”

Preoperative management of giant retroperitoneal schwannoma: A case report and review of the literature

Schwannomas rarely occur in the retroperitoneum, and are normally not aggressive. Preoperative diagnosis is difficult and the surgeon may confront blood vessels, nerves or organs damage, since the intra-operative findings are various. The diagnosis and treatment of malignant schwannomas in the retroperitoneum are even more challenging. In addition, the prognosis of malignant schwannomas is extremely poor. The present study reports the case of a 52-year-old woman who presented with a 6-month history of an abdominal mass in the left lower quadrant. The local doctor determined a preliminary diagnosis of abdominal giant tumor and referred the patient to the First Affiliated Hospital, Medical School of Xi'an Jiaotong University, (Xi'an, China). Following discussion, the patient underwent a surgical resection. Low-grade malignant schwannoma was diagnosed following histological examination. No evidence of recurrence or any other complication was observed at the 18-month follow-up examination. The present study reports a case of giant retroperitoneal schwannoma (RS), and includes a literature review in order to provide an overview of the diagnosis, treatment and prognosis of RS and discuss preoperative management strategies for the disease.

Schwannomas, peripheral nerve sheath tumours arising from Schwann cells, are often associated with inherited disorders such as neurofibromatosis. Gastrointestinal schwannomas, while rare, have been reported in those without personal or family history of neurofibromatosis. Diagnoses of these lesions, however, typically follow evaluations prompted by symptomatic presentations associated with abdominal pain, rectal bleeding, change in bowel habits or positive results on faecal occult blood tests performed for colorectal cancer screening. Further, management of these predominantly benign lesions commonly incorporates surgical resection. We present the case of a sigmoid schwannoma found in an asymptomatic individual on first screening colonoscopy and treated with complete endoscopic polypectomy with anticipated surveillance colonoscopy.

Resection of an esophageal schwannoma with thoracoscopic surgery: a case report

et al. 2016

BackgroundEsophageal schwannomas are rare primary submucosal esophageal tumors. We herein report a case of an esophageal schwannoma that was difficult to diagnose.Case presentationA 39-year-old woman presented with chief complaints of difficulty swallowing and epigastric pain. Enhanced computed tomography of her chest revealed a tumor mass at the upper thoracic esophagus with internal heterogeneity. 18-Fluorodeoxyglucose positron emission tomography/computed tomography showed a hypermetabolic appearance matching the tumor mass; the accumulation had a maximum standardized uptake value of 5.5. We performed endoscopic ultrasound-guided fine-needle aspiration biopsy under general anesthesia, but the small specimens obtained prevented a definitive diagnosis. Thoracoscopic esophagectomy was performed due to the large size of the tumor, suspicion of its malignant potential, and the patient’s symptoms. Histopathological examination revealed spindle-shaped cells in a fasciculated and disarrayed architecture in the proper muscle layer. Immunohistochemical studies showed S100 protein positivity and the absence of CD34 and c-kit. We diagnosed the tumor as a benign schwannoma.ConclusionsWe herein report a relatively rare case of schwannoma of the esophagus that was diagnosed with difficulty.
