RESUMO
Xanthogranulomatous cholecystitis (XGC) is a destructive form of chronic cholecystitis. In some patients it coexists with gall bladder carcinoma (GBC) and is often difficult to differentiate between the two. Present study was performed with an aim to identify differentiating features of XGC and those of XGC with associated Gall bladder carcinoma (XGC ass. GBC). A retrospective analysis of prospectively maintained data of 4800 cholecystectomies performed from January 1988 to December 2003 was carried out. On histopathology 453 cholecystectomy specimens revealed XGC. These patients were divided into two groups, those with associated GBC (n=26) and those without GBC (n=427). Clinical, radiological and operative findings were compared in these two groups. P value of < 0.05 was considered statistically significant. The incidence of associated GBC in present series was 6%. XGC patients with associated GBC, at presentation were older than those with XGC alone and there was male preponderance. XGC patients with associated GBC were more likely to present with anorexia, weight loss, palpable lump and jaundice. Gall stones were present in majority of patients in both the groups. GB wall thickening, GB mass, enlarged abdominal lymph nodes may be found on imaging in both the groups but more so in patients with associated GBC. Both preoperative FNAC and peroperative FNAC/imprint cytology failed to reveal the associated GBC with XGC in some patients.
