Successful endoscopic submucosal dissection of an esophageal granular cell tumor in a pediatric patient: A case report and a therapeutic insight

Abstract

AbstractEsophageal granular cell tumors (GCTs) are rare mesenchymal neoplasms that originate from the Schwann cells of the neural sheath in the esophageal wall. Esophageal GCTs represent approximately 2% of all GCTs. Most cases of esophageal GCT occur in adults with few cases reported in pediatric patients. Although typically benign, these tumors can occasionally exhibit malignant behavior, necessitating timely and appropriate intervention. Traditionally, surgical resection was considered for treatment, nonetheless, considering the invasive nature of such interventions, endoscopic approaches have been developed for diagnosis and treatment. Endoscopic approaches have been shown to lead to serious complications at times, such as incomplete resection or perforation. Here, we present a successful application of endoscopic submucosal dissection in the treatment of an adolescent female patient with esophageal GCT which was discovered during her prior esophagogastroduodenoscopy for vomiting.
