Esophageal Granular Cell Tumor Associated With Eosinophilic Gastrointestinal Disease.

Granular cell tumors (GCTs) are typically benign lesions that can occur in the gastrointestinal tract. Eosinophilic gastrointestinal disease, including eosinophilic esophagitis (EoE), is an immune-mediated condition characterized by eosinophil-predominant inflammation in the gastrointestinal tract. We review previously reported cases of EoE associated with GCTs. To our knowledge, we present the first case of esophageal GCT in a patient with a long history of eosinophilic gastrointestinal disease and likely several years of active EoE before esophageal GCT diagnosis.
