Stemming from smooth muscle, 90% of GISTs, or leiomyomas, are found in the lower two thirds of the esophagus. Typically solitary, multiple tumors (leiomyomatosis) are occasionally reported. Remaining intramural during their growth, most of their bulk protrudes toward the esophageal outer wall, with a freely-movable, normal-looking overlying mucosa. In this study, we report a rare case of esophageal leiomyomatosis treated by esophagectomy. "n"n Case Report: A 70-year-old man presented with discomfort upon swallowing, dysphagia, nausea, belching and weight loss. After a barium swallow, only dilatation of the esophagus from the retained food and saliva was seen. CT scan revealed a 10-cm dilatation of the thoracic esophagus. An endoscopy and upper GI series was performed, but no pathology was found. Esophageal manometry and pH monitoring for gastroesophageal reflux were normal. Upon endoscopic ultrasonography, a thickening of the esophageal wall was identified 20-30 cm from the dental arch. The patient was diagnosed with a GIST, referred to surgeon and a transhiatal esophagectomy was performed. The patient was discharged from the hospital in good condition and has had no problem during the one-year period of follow up.
