A Rare Posterior Mediastinal Mass: Esophageal Leiomyoma
(Derman Medical Publ, 2014) Ozturk, Omur; Karapolat, Sami; Ates, Hakan; Iskender, Abdulkadir; Erdem, Havva
Less than 0.5% of esophagus masses in the posterior mediastinum consist of smooth muscle tumors. In this group; esophageal leiomyomas are often settled in the middle or the lower 1 / 3 parts of the esophagus, and appears as singlewell demarcated submucosal masses. A 25-year-old female followed for 4 years with diagnosis of gastroesophageal reflux and symptoms do not respond to the medical treatment. We performed esophagoduodenoscopy, and observed external pressure to lower 1 / 3 part of esophagus. In thorax tomography and magnetic resonance imaging, we determined a properly defined, approximately 4 x 4 cm sized a solid mass, located in the esophagus wall on the right posterior mediastinum. The mass was separated from muscle and mucosa tissues of the esophagus, and resected totally via right posterolateral thoracotomy. The diagnosis of leiomyoma was based on the histopathological examination. She was asymptomatic both clinically and radiologically after 6 months follow-up. Esophageal leiomyomas should be kept in mind in patients with posterior mediastinal masses with dyspeptic complaints that do not respond to medical treatment.
