Abstract:Hamartomatous Polyposis Syndromes (HPS) are rare hereditary diseases, which include Juvenile polyposis syndrome, PTEN hamartoma tumor syndrome, Peutz-Jeghers syndrome and hereditary mixed polyposis syndrome. HPS is featured by the existence of hamartomatous polyps in the gastrointestinal tract. The typical clinical manifestation of HPS includes melena, proctorrhagia, anemia as well as extra-intestinal findings such as dermatological features and hypoevolutism. Currently, the diagnosis of HPS is mainly depends on its clinical manifestation, but owning to its various features, there still exists much difficulty in accurate diagnosing. Nowadays, as the fast development of genetic technology, many genes have been identified to be associated with HPS, which bring us the hope to monitor, diagnose and treat this disease. In this review, we will discuss the latest development of HPS focusing on its clinical and genetic manifestation, pathological features and its therapeutic aspects.
