[Xanthogranulomatous cholecystitis: report of 2 cases].

Two cases of xanthogranulomatous cholecystitis (XGC) are reported. The pathological characteristics, diagnosis, and treatment of the XGC were discussed with review of the literature. Clinically this disease was often misdiagnosed as gallbladder carcinoma. Microscopically, the nodules or tumor-like masses contained foamy histiocytes, cells of inflammation, and fibroblasts. The wall of the gallbladder was yellowish, nodulated, and markedly irregular thickened.
