Summary
Benign schwannomas are rare tumors originating from Schwann cells. This case report details an extremely rare instance of extrahepatic biliary schwannoma associated with bile duct stones.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Pathology
- Oncology
Background:
- Schwannomas, benign tumors of Schwann cells, commonly affect the central nervous system and extremities.
- Biliary tract schwannomas are exceptionally rare, often presenting with obstructive jaundice.
- Extrahepatic biliary tumors are uncommon, necessitating thorough investigation of rare pathologies.
Observation:
- A 64-year-old female presented with intra- and extrahepatic bile duct and gallbladder stones detected during screening.
- Imaging revealed an extrahepatic biliary mass.
- The patient underwent surgical resection for the mass and stones.
Findings:
- Histopathological examination confirmed the diagnosis of benign extrahepatic biliary schwannoma.
- The schwannoma was found incidentally in association with bile duct stones.
- No evidence of malignancy was observed.
Implications:
- This case highlights the potential for benign schwannomas to occur in the biliary tract, even without typical obstructive symptoms.
- The association of extrahepatic biliary schwannoma with bile duct stones is unprecedented in medical literature.
- Increased awareness may aid in the diagnosis of rare biliary tract neoplasms.
