A rare case of carcinoid tumor of the gallbladder was reported. The patient was a 40-year-old man with a chief complaint of nausea and epigastralgia on the 2nd of March in 1991. US, DIC, CT and ERCP revealed a 15mm-sized polypoid lesion at the neck of the gallbladder. Cholecystectomy was performed. The resected specimen contained no stones. A yellowish-white 15×10mm-sized sessile polyp was noted at the neck of the gallbladder. Microscopically, the polyp showed a nodular proliferation of uniform cuboidal tumor cells which revealed positivity for Grimelius staining, and was covered by ordinary gallbladder epithelium. Immunohistochemically, these cells revealed positivity for Neuron -Specific-Enolase.
