Summary
Xanthogranulomatous cholecystitis presents similarly to gallstones but with more complications. This benign gallbladder condition can mimic cancer, highlighting the importance of frozen-section biopsy for accurate diagnosis.
Area of Science:
- Gastroenterology
- Pathology
- Surgical Oncology
Background:
- Xanthogranulomatous cholecystitis (XGC) is a rare, severe form of chronic cholecystitis.
- It often presents with symptoms overlapping gallstone disease (cholelithiasis).
Purpose of the Study:
- To review clinical, radiological, and pathological findings in patients with xanthogranulomatous cholecystitis.
- To differentiate XGC from gallbladder carcinoma based on imaging and intraoperative findings.
Main Methods:
- Retrospective review of 31 patients diagnosed with xanthogranulomatous cholecystitis.
- Analysis of clinical presentation, radiological imaging (ultrasonography), intraoperative findings, and pathological results.
Main Results:
- Patients typically presented with gallstones; biliary colic was less frequent (17%) compared to cholelithiasis.
- Complications such as biliary fistula (4 patients) and gallbladder perforation with abscess (4 patients) were noted.
- Radiological and intraoperative findings often mimicked gallbladder carcinoma, with xanthogranulomatous tissue invading adjacent structures.
- Xanthogranulomatous cholecystitis coexisted with gallbladder carcinoma in three patients.
Conclusions:
- Xanthogranulomatous cholecystitis shares clinical similarities with gallstone disease but has a higher complication rate.
- The condition can be misdiagnosed as gallbladder cancer due to its invasive appearance.
- Frozen-section biopsy is crucial for distinguishing between XGC and malignancy, enabling appropriate surgical management.
