Adenocarcinoma of the colon associated with hyperplastic polyposis.
A 24-year-old woman presented with a history of chronic watery diarrhea associated to abdominal pain and weight loss. Her father had died of cirrhosis at the age of 47 and her grandmother had died from colorectal cancer at the age of 69. A colonoscopy revealed multiple sessile polyps scattered throughout the colon (ranging from 3 to 15mm), and a large, villous looking lesion located in the asce...
متن کاملInverted hyperplastic polyposis of the colon.
AIMS To describe and evaluate two apparently unique cases of inverted hyperplastic (metaplastic) polyposis of the colon. METHODS The cases were analysed by standard histopathological, histochemical, and immunohistochemical techniques and the findings compared with those of regular hyperplastic polyps of the colorectum. RESULTS Both patients were middle-aged men with concurrent adenocarcinom...
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...
متن کاملDevelopment of invasive colon cancer with microsatellite instability in a patient with hyperplastic polyposis syndrome.
The serrated pathway has recently been proposed as a route for the development of colorectal cancer with microsatellite instability. Hyperplastic polyposis syndrome is a rare syndrome defined by the presence of numerous serrated polyps, with a high risk of developing into colorectal cancer. We present here a case of hyperplastic polyposis syndrome developing into colorectal cancer with microsat...
متن کاملAdenomatous polyposis coli gene mutations in ulcerative colitis-associated dysplasias and cancers versus sporadic colon neoplasms.
Adenomatous polyposis coli (APC) gene mutations occur in most sporadic colonic adenomas and carcinomas. Precursor lesions of ulcerative colitis (UC)-associated colon carcinomas, although morphologically similar to sporadic adenomas, may be biologically distinct from them and are, in fact, managed differently. Since sporadic adenomas may also occur in UC, a method of discriminating between these...
