Multifocal Synchronous Granular Cell Tumors of the Gastrointestinal Tract.

Granular cell tumors (GCT) are rare and unusual tumors, which are usually benign and asymptomatic. Only 5-10% of cases involve the gastrointestinal tract, most commonly as singular, non-cancerous lesions in the esophagus. We report a rare case of symptomatic, multifocal, synchronous GCT involving the esophagus, stomach, and cecum.
