Gastric granular cell tumour, a rare entity.

Granular cell tumours are rare neoplasms that may occur anywhere in the body. The most common locations are the oral cavity, skin and subcutaneous tissue, with only 8% of these tumours occurring at a gastrointestinal site. In the specific case of gastric granular cell tumours, only a few cases have been published until today. Granular cell tumours are usually benign; however, some malignant forms have been reported. Both endoscopic and surgical resection represent the treatment of choice. The authors report a new clinical case of a gastric granular cell tumour, treated with laparoscopic surgical resection, describing some endoscopic, imagiological and anatomopathological features. © BMJ Publishing Group Limited 2019.
