Though leiomyoma is the most common benign esophageal tumor, it is rare in the upper third of esophagus. Recently, we experienced two cases of esophageal leiomyoma in the upper third of esophagus. The patient were a 53 year old female and a 40 year old male. On esophagoscopy, masses were found at 20ulcorner23 cm, 22ulcorner26 cm from upper incisor with normal overlying mucosa. Enucleation was done through a right posterolateral thoracotomy without complications.
