We present a case of benign esophageal leiomyoma with video-assisted thoracic enucleation. A 39-year-old woman was found to have an abnormal shadow in the mediastinum on a chest X-ray on a medical check-up. Chest CT performed for the purpose of close examination revealed a tumor with a size of 62×33 mm from the middle intrathoracic esophagus to the lower esophagus. Upper gastrointestinal endoscopy revealed a left half-circumferential elastic soft submucosal bulge in the thoracic middle-lower esophagus. Endoscopic ultrasonographic fine-needle aspiration biopsy(EUS-FNA)was performed, and immunostaining showed positive muscular markers SMA, but negative for CD34, c-kit, and S-100, and the diagnosis was esophageal leiomyoma. Therefore, thoracoscopic-assisted esophageal leiomyoma resection was performed. Postoperative immunohistological examination showed positive for SMA and Desmin, and the diagnosis was leiomyoma.
