Sažetak
Multiple primary cancers occurring in the same patients have been reported to represent 1.8-3.9% of all cancers. The majority of all patients reported to have had a combination of simultaneous neoplastic changes in the ampulla of Vater and the colon showed familial adenomatous polyposis (FAP) syndrome. Variants of familial adenomatous polyposis coli are: attenuated adenomatous polyposis coli (AAPC, previously also known as flat adenoma syndrome) and multiple adenoma coli. AAPC is characterized clinically by many, but usually fewer than 100, colonic lesions that are characteristically slightly elevated and plaque- like, with a reddish surface and sometimes central depression. Genetically it represents an extremely rare variant of FAP. Another group of individuals, so-called multiple adenoma patients, have a phenotype similar to AAPC, but most have no demonstrable germ-line adenomatous polyposis coli mutation, as do patients with FAP or AAPC. However, there have been only a few reports that discussed concurrent neoplastic changes in the ampulla of Vater and colon in patients with multiple colonic flat adenomas, but without the florid phenotype of classical FAP. We present rare clinical course of a patient with multiple (more than 60) flat adenomas in the proximal colon and two primary cancers: of the ampulla of Vater and of the ascending colon. This patient and his family history did not show polyposis compatible with FAP or hereditary nonpolyposis colorectal cancer (HNPCC) syndrome.
