Abstract

Adenomyoma is a nonneoplastic lesion that can be found anywhere in the gastrointestinal tract, but it's rarely found in the extrahepatic bile duct. To the best of our knowledge, it is a completely benign lesion, but making a clear distinction from malignancy on preoperative evaluation is very difficult. Its clinical importance mainly lies in the possibility that they may be confused with carcinoma, leading to unnecessarily extensive surgical resections. We report here on a case of distal common bile duct adenomyoma that presented with right upper quadrant abdominal pain, and the preoperative examinations could not reveal whether the tumor was benign or malignant. It was finally diagnosed by histological examination after performing pylorus preserving pancreaticoduodenectomy.
