Summary
Biliary hamartoma, a benign liver lesion, is often mistaken for cancer due to its appearance. Recognizing key features helps avoid misdiagnosis of this ductal plate malformation.
Area of Science:
- Hepatology
- Gastroenterology
- Pathology
Background:
- Biliary hamartoma (Von Meyenburg complex) is a rare, benign liver lesion.
- It is considered a ductal plate malformation, not a true neoplasm.
- Often presents as multiple, small, subcapsular liver nodules.
Observation:
- Lesions are frequently discovered incidentally during imaging or surgery.
- The appearance can mimic metastatic liver nodules.
- Histological features may also be misleading.
Findings:
- Two cases are presented: a 94-year-old woman and a 48-year-old man.
- Both cases involved incidental findings during imaging and surgery.
- One case was initially misdiagnosed as adenocarcinoma.
Implications:
- Accurate differentiation from malignant lesions is crucial.
- Understanding clinical and pathological findings aids in correct diagnosis.
- Avoids unnecessary treatment for a benign condition.
