摘　　要：Schwannoma is a myelin sheath tumor complicated with neurofibroma, neurofibromatosis and neurogenic sarcoma. Peripheral nerve sheath tumors represent 2%-6% of gastrointestinal tract stromal tumors (GIST), but there are deficient data about location of neurogenic tumors in the biliary system and only nine cases of schwannoma of the extrahepatic biliary tract have been reported. These tumors are clinically non-specific. They are usually symptomatic by compressing the close or adjacent structures when being retroperitoneal, and their preoperative diagnosis is extremely difficult. This paper reviews the literature data and describes a case of schwannoma of the common bile duct associated with cholestasis in a healthy young woman, diagnosed and treated in our department. This case is of interest on account of the complexity of its diagnosis and the atypical macroscopic growth pattern of the tumor.Schwannoma is a myelin sheath tumor complicated with neurofibroma, neurofibromatosis and neurogenic sarcoma.
