Esophageal granular cell tumor removed by endoscopic polypectomy.
Granular cell tumors are rare neoplasms that are generally benign. They are usually found in the tongue, subcutaneous tissues, and breast. Since Abrikossof first described the histology of this tumor in 1926, there have been 86 cases involving the esophagus discussed in the literature. There is a low likelihood of these tumors becoming malignant and recurrence after resection is rare. However, these tumors can be confused with more malignant lesions. We report an additional case involving the esophagus and offer new management guidelines in the era of fiberoptic endoscopy.
