We report a schwannoma of the gallbladder in a 58-year-old man who was diagnosed as cholecystolithiasis. He presented with recurrent episodes of abdominal pain in the right upper quadrant. The abdominal computed tomography scan and ultrasonography revealed stones about 15 mm in diameter in the gallbladder. Under the diagnosis of cholecystolithiasis, laparoscopic cholecystectomy was performed. The resected specimen showed chronic cholecystitis and no suspicion of neoplasm. Pathological examination revealed that the tumor consist of spindle cells without atypical appearance at small area of fundus. Immunohistologically, tumor cells were positive for S-100 protein and negative for alpha-SMA and c-kit, the lesion was diagnosed as schwannoma.
