ABSTRACT
Antecedentes: la poliposis hiperplásica es una enfermedad esporádica, con bases genéticas poco conocidas, que se manifiesta usualmente alrededor de los 50 años de edad. Posee un riesgo aumentado para el cáncer colorrectal, el cual ha sido citado de hasta un 50 % en diferentes series de la literatura. En su patogénesis ha sido implicada la secuencia pólipo hiperplásico-adenoma serrato-cáncer colorrectal. Objetivo: presentar un caso clínico y realizar una revisión bibliográfica del tema, especialmente en relación con su pesquisa y manejo. Lugar de realización: Institución pública. Población: un paciente de 54 años de edad evaluado y tratado por cáncer de recto y poliposis hiperplásica. Método: presentación de un caso y análisis bibliográfico. Conclusiones: la poliposis hiperplásica es una enfermedad fenotípicamente heterogénica y los individuos afectados tienen riesgo aumentado para desarrollar un cáncer colorrectal.
Background: Hyperplastic polyposis is a sporadic disease, with little known genetic basis that usually present at around 50 years old. It has an increased risk of colorectal cancer up to 50%, according to different series of the literature. With regard to the pathogenesis a sequence of hyperplastic polyposisserrated adenoma-colorectal cancer has been involved. Objective: To report on a case and to make a literature review on this subject, especially with relation to the screening and management. Place of application: Public Institution. Population: 54 years old patient evaluated and treated for rectal cancer and hyperplastic polyposis. Method: case report and literature review. Conclusions: hyperplastic polyposis is a phenotypicaly heterogeneous disease and affected individuals are at increased risk for colorectal cancer.

Polyp is a descriptive term used with reference to any mass of tisue that projects outward from the normal surface of th gastrointestinal tract. Morson and col. classified this disorder in 1962 in two categories: non-neoplasic (hamartomas) and neoplasic (tubular, villous and mixed). At preent, they are classified between polypoid formations termed serrated polyps, out of whom some can be assigned as potentially malignant. The author of this report describe successively the foloowing conditions: mlignant colorectal polyps, are those presenting an invasive carcinoma, that is with penetration through the muscularis mucosae, involving the regional lymph nodes. Other types: intestinal polyposis, familial adenomatous polyposis Turcot syndrome (malingnant tumors of the central nervous system associated with familial polyposis of the colon) juvenile polyposis; Cowden disease: described since the disease suffered by the patient Rachel Cowden (also termed as multiple hamartomas syndrome) hereditary and preneoplasic with autosomic and dominant transmission, Peutz-Jeghers syndrome: hereditary disease with autonomic and dominant transmission, characterized by a harmatous gastrointestinal polyposis with melanin pigmentation of the skin, and melanin spots of the bucal mucous membrane. Bleeding and anemia are frequent complications. Syndrome of De Ruvalcalva-Myre-Smith: associates hamartosus polyposis juvenile and other disorders as macrocephalia, psychomotor madurative delay and pigmentary changes of the genitalia, and Cronkhite-Canada syndrome, a generalized gastrointestinal polyposis, even those considered benign, can suffer by different causes, a malignant transformation. The author also refers the surgical manament, adenomas and malignant transformation and the development of carcinogenesis. The genetic of adenomas and colerectal cancer, are also considered.
