Background/aim: Hepatic xanthogranuloma is a very rale disease and formation process is unknown.
Case Report: A 69-year-old woman previously diagnosed as simple liver cyst. Two years before, a 36-mm liver cyst was found in segment 5, while one year later, the hemorrhagic cyst was 40 mm in diameter and a thin septum had formed. The most recent T1-weighted magnetic resonance imaging (MRI) showed a regular 21-mm hepatic mass with a hyperintense 11-mm center and a hypointense periphery. Peripheral enhancement was seen on gadolinium enhanced MRI. Hepatobiliary cystadenoma or cystadenocarcinoma was suspected because of wall thickness and slight enhancement. Microscopic examination following laparoscopic partial liver resection revealed fibroblasts, dense collagen fibers, and a double layer of hemosiderin-laden as well as foamy macrophages attached to the fibrous capsule.
Conclusion: The patient was diagnosed with a hepatic xanthogranuloma that originated from a hemorrhagic liver cyst. Intracystic hemorrhage may be one of the reasons for hepatic xanthogranuloma formation.

Introduction: Xanthogranulomatous Cholecystitis (XGC) is a rare inflammatory condition characterized by the presence of xanthogranulomas within the gallbladder wall, often mimicking gallbladder carcinoma (GBC). Diagnosis is challenging and may require biopsy. Once GBC is excluded, an open cholecystectomy is recommended, although laparoscopic cholecystectomy is increasingly being performed with great caution.

Article Synopsis
- - Hepatic cysts are generally harmless and often don't show symptoms, but larger ones can lead to issues like jaundice and portal hypertension, although they rarely obstruct the gastrointestinal tract.
- - In a reported case, a large hepatic cyst caused a blockage in the duodenum, requiring an emergency procedure where the cyst was punctured to relieve pressure and examine the fluid for malignancy, which returned negative results.
- - To treat the cyst, laparoscopic deroofing was performed, but due to the cyst being strongly attached to the duodenal wall, the wall was left intact, demonstrating that a two-step method of cyst puncture followed by surgery might be effective in urgent cases.
Xanthogranulomatous cholecystitis on fusion of the planes of the liver.

Xanthogranulomatous cholecystitis (CXG) is a rare entity of cholecystitis, characterized by the presence of xanthogranulomas within the gallbladder wall, that could be misdiagnosed as a vesicular carcinoma. We report a case of 66-year-old man with xanthogranulomatous cholecystitis associated with an incidental finding of a fusion of the planes of the liver which is a rare anatomic variant. Imaging especially ultrasounds, CT scan, and MRI play a key role in the characterization of those anomaly, thus avoiding a non-suitable surgical procedure.

Langerhans cell histiocytosis, Rosai-Dorfman disease, and juvenile xanthogranuloma may present at birth or any time afterward. Some patients have minimal skin or lymph node involvement, but others present with life-threatening pulmonary, hepatic, bone marrow, or central nervous system lesions. There is often a delay in diagnosis because of confusing overlap with more common neonatal diseases.
