Abstract

A 75-year-old male was referred to our hospital for further evaluation of an esophageal submucosal tumor. He was asymptomatic. Computed tomography revealed a completely calcified, 34 mm × 18 mm mass at the posterior mediastinum. Endoscopic observations revealed an elevated lesion in the anterior wall of the esophagus, localized 28 cm from the incisor teeth and covered with normal mucosa. Mucosal cutting biopsy was performed. Histopathological examination of the biopsy specimen confirmed the diagnosis of esophageal leiomyoma. He has undergone follow-up observation but no treatment. Esophageal leiomyoma with diffuse calcification is rare, and preoperative diagnosis is difficult. Mucosal cutting biopsy was useful for diagnosis in this case.
