Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms that mainly occur in the stomach and small intestine; those arising esophagus rarer. A 54-year-old woman was referred to our hospital with a one-month history of dysphagia. Esophagogastroduodenoscopy (EGD), performed approximately five months earlier, had not revealed any specific findings. However, an EGD showed presence round, protruding lesion (approximately 40×30 mm size), normal overlying mucosal surface, 35–39 cm from upper incisor. Chest computed tomography (CT) large esophageal mass. Enucleation on mass, GIST diagnosed using immunochemical staining. Imatinib mesylate administration initiated two postoperatively. The patient stable, without evident recurrence 8-month postoperative follow-up chest CT examinations. Therefore, physicians should consider patients worsening dysphagia may have underlying organic condition, such as acute increase size GIST, even if recent examinations were unremarkable.
