Gardners syndrome (GS) is a variant of familial adenomatous polyposis (FAP) and presents with both colonic and extra colonic manifestations. It is an autosomal dominant disorder and results from mutations in adenomatous polyposis coli (APC) gene. Patients with GS if not treated early will invariably develop colonic cancers at a much younger age than those with sporadic colonic carcinoma. These patients also develop other malignant tumours like duodenal cancers, gastric cancer, hepatoblastoma, papillary carcinoma of the thyroid and multifocal cholangiocarcinomas. With early diagnosis and treatment of colonic polyposis, adenocarcinoma of the duodenum has become the leading cause of death in FAP patients. The mean age at which duodenal carcinoma is diagnosed in FAP is 45-52 years. We report the rare occurrence of duodenal carcinoma as the presenting feature of Gardner’s syndrome in a young 25-year-old male with no obvious malignant changes in the colonic adenomas.

Turcot’s syndrome is a rare genetic disorder clinically characterised by concomitant occurrence of primary brain tumour and colorectal polyposis. It is commonly seen in association with two other syndromes, namely, hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP). It is characterized by an increased risk for early onset of other tumours including of endometrium, stomach, small intestine, hepatobiliary system, kidney, ureter, brain and ovary. We report the rare occurrence of Turcot syndrome in a 13-year-old girl who presented with focal seizure.
