| Abstract: | Xanthogranulomatous cholecystitis (XGC) is a rare, benign, destructive inflammatory disease of the gallbladder that is assumed to be a variant of chronic cholecystitis. We herein present a rare case of XGC, which simulates gallbladder carcinoma with extensive involvement of the liver, omentum and the biliary trees. At surgery, total cholecystectomy with partial hepatectomy of the gallbladder bed and excision of adjacent xanthogranulomatous tissue was performed, but bilio‐enteric anastomosis for biliary decompression, which was the procedure preoperatively planned, was impossible to indicate because the common bile duct could not be clearly exposed by its infiltration showing mass formation. Therefore, retrograde transhepatic biliary drainage was eventually indicated for subsequent endoscopic therapy using stent placement to deal with the biliary structure caused by XGC. The patient has been leading a normal life after stent placement in the biliary tract for 6 months duration without any symptoms suggesting biliary stricture. In conclusion, XGC can simulate gallbladder cancer in its clinical presentation, radiological findings and even gross operative features. It is important to make preoperative ultrasound‐guided fine‐needle aspiration cytological diagnosis or intraoperative pathological diagnosis in order to avoid misdiagnosis and unnecessary therapy. Cholecystectomy, excision of adjacent xanthogranulomatous tissue, which often includes partial hepatic resection, are still the best management of XGC. |
