Monoclonal antibodies raised by synthetic peptide immunisation were used to determine the distribution of the protein product of the c-myc gene by immunocytochemical staining of archival wax embedded material from patients with familial adenomatous polyposis. Polyps from 18 cases of familial adenomatous polyposis, 10 of whom had developed malignant change, and 30 normal control colonic biopsy s...

We present a case of a 25-year-old female with diagnosed familial adenomatous polyposis and elevated carcinoembryonic antigen with negative family history. The suspicion of Gardner's syndrome was raised because extirpation of an osteoma of the left temporo-occipital region was made 10 years ago. Restorative procto-colectomy and ileal pouch anal anastomosis was made but histology delineated aden...

Extra-abdominal desmoid tumors are a significant cause of morbidity in patients with familial adenomatous polyposis syndrome. Understanding of the basic biology and natural history of these tumors has increased substantially over the past decade. Accordingly, medical and surgical management of desmoid tumors has also evolved. This paper analyzes recent evidence pertaining to the epidemiology, m...

COLORECTAL CANCER IS CLASSIFIED IN TO THREE FORMS sporadic (70-75%), familial (20-25%) and hereditary (5-10%). hereditary colorectal cancer syndromes classified into two different subtypes: polyposis and non polyposis. Familial Adenomatous polyposis (FAP; OMIM #175100) is the most common polyposis syndrome, account for <1% of colorectal cancer incidence and characterized by germline mutations i...

INTRODUCTION Splenoma or splenic hamartoma is a rare primary splenic tumor most often discovered radiologically and incidentally. Splenic hamartomas have a strong association with solid and hematological malignancies and, in rare cases, with tuberous sclerosis, but to the best of our knowledge no reports of splenic hamartomas associated with familial adenomatous polyposis have been documented, ...

Resection of the colon in patients with familial adenomatous polyposis frequently results in the regression of polyps in the remaining rectum, suggesting a reduction of cellular proliferation. These patients remain at risk of developing rectal cancer but whether this risk increases with time is uncertain. Since ornithine decarboxylase activity is associated with cellular proliferation, mucosal ...

INTRODUCTION Ileal adenomas associated with familial adenomatous polyposis are a common finding. Many recent studies following panproctocolectomy for familial adenomatous polyposis have confirmed the presence of multiple ileal adenomas and an increase in ileal mucosal proliferation. In this study, we present a case of invasive adenocarcinoma arising in a severely dysplastic tubulovillous adenom...
