Abstract
|
|
|
|
Esophageal leiomyoma is a benign tumor that accounts for two-thirds of esophageal benign tumors. In general, patients with esophageal leiomyoma are asymptomatic; however, as the tumor grows in size, symptoms such as dysphagia, chest discomfort, obstruction, or bleeding can appear. A 65-year-old man visited our clinic to receive treatment for a subepithelial tumor in the lower esophagus, which was incidentally found during endoscopy for work-up of chest discomfort and indigestion. On endoscopic ultrasonography (EUS), the tumor was 2.6×1.9 cm in size, with a cystic lesion located in the submucosal and proper muscle layers and thick cystic wall. Therefore, it was highly likely to be a duplication cyst. As the patient had symptoms such as chest discomfort, surgical resection was performed. The tumor was finally diagnosed as a leiomyoma with cystic degeneration. Leiomyoma with cystic change that has similar EUS features to duplication cyst is rare. Thus, we report the case with a literature review.
