BACKGROUND: Granular cell tumors (GCT) in the gastrointestinal tract are rare. Herein, we describe a case of a gastric GCT diagnosed preoperatively by endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) and successfully resected by single-incision laparoscopic surgery (SILS). CASE PRESENTATION: A 46-year-old Japanese woman had a tumor located in the angle of the stomach that was approximately 1.5 cm in diameter. Abdominal computed tomography (CT) revealed a submucosal tumor (SMT), which was finally diagnosed as a gastric GCT using EUS-FNAB. The tumor was not identified by CT 1 year and 4 months before diagnosis; therefore, because there was a possibility that the tumor was malignant, we performed surgical wedge resection using SILS. The patient had an uneventful recovery postoperatively and was discharged without complications 3 days after surgery. The tumor was pathologically diagnosed as a benign GCT that remained within the muscular layer. No recurrence or complications have occurred in the first 16 months since the surgery. CONCLUSION: Because gastric GCTs are generally benign and are rarely associated with lymph node metastasis, SILS seems to be a safe and feasible surgical approach for treating GCTs.
