Endoscopic Removal of Granular Cell Tumors of Stomach: Case Report and Review of Literature

Gastrointestinal granular cell tumors (GCTs), usually benign, soft-tissue tumors, are thought to arise from Schwann cells that may occur at many sites. Only 5-7% of these lesions are detected in the gastrointestinal tract. Histologically, it is composed of sheets or nests of plump round or polygonal...

Sumario:Gastrointestinal granular cell tumors (GCTs), usually benign, soft-tissue tumors, are thought to arise from Schwann cells that may occur at many sites. Only 5-7% of these lesions are detected in the gastrointestinal tract. Histologically, it is composed of sheets or nests of plump round or polygonal cells having abundant slightly amphophilic granular cytoplasm with centrally located uniform pyknotic nuclei and immunohistochemical staining for S-100 protein supports the proposed derivation from Schwann cells. In this study, we reported a case of a solitary GCT of the stomach that was completely removed after endoscopic submuscosal resection.
