TI - Carcinoid tumors of the ampulla of Vater. We reviewed the records of four patients with carcinoid tumor at Vater's ampulla. The findings were compared to a recent review of the previously reported 73 patients. The two groups were similar with respect to male predomina- nce, presenting symptoms, infrequent preoperative diagnosis, tumor size, and rate of metastasis. The present study patients were older by 20 years, and none of the patients in this group had von Recklinghausen's disease, despite a 25 per cent incidence in the review group.
Periampullary carcinoids act differently clinically from the midgut type.
In particular, tumor size appears to have no correlation to metastatic potential, as in midgut carcinoids. I, Kyushu University, Faculty of Medicine, Fukuoka, Japan. Subjects were a consecutive series of 10 patients with XC and 10 with carcinoma, all of whom radiologically showed thickened gallbladder walls. Clinically, XC can be distinguished from gallbladder cancer by cholangiography, calculous findings, and a gallbladder aspirate of pus or nothing.
