title: Xanthogranulomatous cholecystitis versus gallbladder cancer: clinical differentiating factors.
abstract: Xanthogranulomatous cholecystitis (XC) is occasionally difficult to differentiate from gallbladder cancer and mandates efforts to avoid extensive operations. We studied the clinical factors to differentiate XC from cancer. Subjects were a consecutive series of 10 patients with XC and 10 with carcinoma, all of whom radiologically showed thickened gallbladder walls. As opposed to cancer, XC was typified by invisible gallbladders on cholangiography (1), the presence of cholelithiasis (P = 0.01) (2), and, intraoperatively, an aspirate of pus or nothing (P < 0.01) (3). To diagnose XC against gallbladder cancer, (1) and (2) in combination and (3) demonstrated an accuracy of 82.4% and 85.0 per cent, respectively. Clinically, XC can be distinguished from gallbladder cancer by cholangiography, calculous findings, and a gallbladder aspirate of pus or nothing.
