Summary
Bile duct hamartomas, often mistaken for cancer, can present with symptoms like jaundice and pain. This case highlights the importance of accurate diagnosis through pathology to differentiate these benign lesions from malignant tumors.
Area of Science:
- Hepatobiliary Medicine
- Surgical Pathology
- Diagnostic Imaging
Background:
- Biliary hamartomas are rare, benign congenital malformations of the bile ducts.
- They can present with non-specific symptoms, mimicking other hepatobiliary conditions.
- Accurate differentiation from malignancy is crucial for appropriate patient management.
Observation:
- A 63-year-old male presented with fever, jaundice, and right upper quadrant pain.
- Initial imaging suggested hepatocellular carcinoma due to multiple liver lesions.
- Computed tomography and magnetic resonance imaging revealed complex cystic and nodular lesions.
Findings:
- Exploratory laparotomy, cholecystectomy, and liver biopsy were performed.
- Pathology confirmed bile duct hamartomas with associated microabscess formation.
- The patient's presentation was initially misattributed to malignancy.
Implications:
- This case underscores the diagnostic challenges in differentiating bile duct hamartomas from primary liver cancers.
- Histopathological examination remains the gold standard for definitive diagnosis.
- Understanding the imaging characteristics is vital for avoiding unnecessary aggressive treatments.
