Granular cell myoblastoma of the esophagus after irradiation for carcinoma.
Granular cell myoblastoma is an uncommon, usually benign tumor. Only 20 cases are reported in the esophagus. We describe a 65-year-old woman who developed a granular cell myoblastoma of the postericoid esophagus in the area of a squamous cell carcinoma successfully treated with irradiation. To our knowledge, this is the 21st reported case, and the only case occurring in the esophagus after irradiation for primary squamous cell carcinoma.
