Summary
This study reports a rare case of common bile duct adenomyoma in a 51-year-old man. Successful surgical resection achieved a favorable outcome with no recurrence after 12 months, highlighting effective treatment for this uncommon biliary tumor.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Pathology
Background:
- Adenomyomas are rare benign tumors typically found in the uterus.
- Common bile duct adenomyomas are exceptionally rare, presenting diagnostic challenges.
Observation:
- A 51-year-old male presented with jaundice and pruritus, without abdominal pain.
- Imaging studies (CT, MRCP, ultrasonography) suggested a distal bile duct tumor.
- Physical examination revealed only yellowish skin and sclera.
Findings:
- Histological examination confirmed an adenomyoma of the common bile duct, composed of adenoid and myofibrous tissue with moderate atypia.
- Immunophenotyping showed the epithelial component was cytokeratin 7 positive and cytokeratin 20 negative.
- The patient underwent successful pancreaticoduodenectomy.
Implications:
- This case underscores the importance of considering rare diagnoses like adenomyoma in the differential for biliary tract lesions.
- Successful surgical management, such as pancreaticoduodenectomy, can lead to excellent long-term outcomes for common bile duct adenomyomas.
- Further research may elucidate the pathogenesis and optimal management strategies for this rare entity.
