Giant esophageal leiomyoma with secondary megaesophagus.

A 25-year-old woman presented with a giant leiomyoma in the lower third of the esophagus. She had no digestive symptoms, although there was a severe esophageal dilation. Such a megaesophagus secondary to a leiomyoma has not been described previously. Esophagogastric resection was performed, followed by an uneventful recovery period. The literature on esophageal leiomyoma is reviewed.
