Benign tumor and pseudotumor of the gallbladder are infrequently reported in our country. In this paper, 5 patients with benign tumor (3 tubular adenoma, 1 leiomyoma and 1 fibroma) and 35 pseudotumor (26 cholesterol polyps and 9 inflammatory polyps) of the gallbladder are presented. Most patients presented a typical clinical manifestation of chronic cholecystitis. Oral cholecystography gave a lower detection rate. B-ultrasonography was able to show the presence of neoplasm in the gallbladder (37/40). Correct diagnosis was established by operation and pathology. In this series, all patients were cured by cholecystectomy. The authors believe that, for the neoplasms detected by B-ultrasonography with definite clinical symptoms or with a diameter of more than 1.0 cm, cholecystectomy is indicated. For those older or weaker patients with milder symptoms or with neoplasms less than 1.0 cm in diameter, periodic B-ultrasonography follow-up is suggested.
