Résumé
Xanthogranulomatous Cholecystitis (XGC) is an uncommon inflammatory disease. In a retrospective analysis of 159 cholecystectomy specimens revealed 21 cases of diffuse and focal XGC with an overall incidence of 13.2 per cent. The age distribution was identical to those of traditional chronic cholecystitis with female predominance (M:F ratio 1:4). Gallstones were seen in 15 cases with marked thickening of the gall bladder on ultrasonography. In one case it falsely diagnosed as carcinoma on ultrasonographic examination, however, histopathologically it was turned out to be XGC. One case of XGC was associated with adenocarcinoma of gall bladder. The incidence of diffuse XGC was 5.66 per cent, whereas incidence of focal XGC was 7.54 per cent amongst chronic cholecystitis.
