Hyperplastic polyposis syndrome: a call for broader diagnostic criteria
Background Hyperplastic Polyposis Syndrome (HPS) is a rare disease characterized by multiple or large hyperplastic polyps and carries an approximately 40% lifetime colorectal cancer risk. Although a genetic basis has not been established, HPS is believed to be a heritable syndrome and is diagnosed by clinical criteria as set forth by the World Health Organization (WHO). Based on clinical experi...
متن کاملHyperplastic Polyposis Syndrome Identified with a BRAF Mutation
Hyperplastic polyposis syndrome (HPS) is a rare condition characterized by the presence of numerous hyperplastic polyps (HPs) in the colon and rectum. Patients with HPS have an increased risk of colorectal cancer. This link is associated with gene mutations, especially B type Raf kinase (BRAF). However, a case of HPS associated with gene mutations has seldom been reported in Korea. Here, we des...
متن کاملPhenotypic characterization and familial risk in hyperplastic polyposis syndrome.
BACKGROUND. Hyperplastic polyposis syndrome (HPS) is a rare condition characterized by numerous hyperplastic polyps (HP) with a pancolonic distribution. Genetic and environmental factors, including smoking, may be responsible for phenotypic differences. OBJECTIVE. To characterize HPS patients' phenotype and to determine HPS risk and colorectal cancer (CRC) risk in the first-degree relatives (FD...
متن کاملHyperplastic polyposis syndrome: endoscopic imaging, phenotypic charcteristics and molecular pathways
Phenotypic characteristics Hyperplastic polyposis syndrome (HPS) is a heterogeneous condition involving colorectal serrated polyps and is associated with an increased colorectal cancer (CRC) risk. We evaluated the clinicopathological features of HPS patients and their first-degree relatives. Previously published case series report CRC at clinical presentation in up to 50% of HPS patients. We an...
متن کاملThe polypoid ganglioneuroma associated with hyperplastic polyposis
Ganglioneuroma (GN) of the gastroin-testinal (GI) tract is rare tumor composed of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Diffuse ganglioneuromatosis is associated with multiple endocrine neoplasia IIB (MEN IIB), neurofibro-matosis type I (NF1, also known as von Recklinghausen disease), multiple cu-taneous or GI tract neurofibromatosis, and neurogenic s...
