Leiomyoma of the esophagus.

A review of the clinical records from 1947 to 1984 of the Istituto Nazionale Tumori of Milan provided 20 cases (14 males and 6 females) of esophageal leiomyoma. Eighteen of the tumors were in the thoracic esophagus and 2 were at the cardiac level. The most frequent symptoms were dysphagia, slight epigastralgia and odynophagia. Differential diagnosis should be made with mediastinic neoplasms and esophageal cancer. Barium swallow and esophagoscopy are the most sensitive procedures for a correct preoperative diagnosis. Surgery is mandatory because of the tendency to a continuous endoluminal growth (in 97% of the cases) and a possible malignant transformation. However, surgery is conservative: extramucosal enucleation of the leiomyoma is the procedure of choice. The long-term results are excellent, and morbidity is acceptable.
