BACKGROUND: Familial adenomatous polyposis (FAP) is a rare, autosomal dominant disease clinically characterized by the early onset of many adenomatous polyps throughout the colon, which turn into colon cancer, if left untreated. In FAP patients, polyps can also occur in the upper gastrointestinal (GI) tract, especially in the duodenum. Adenomas beyond duodenum are rare and mostly located in the proximal jejunum and distal ileum. The management of such polyps can be either surgical or endoscopic, depending on the features of the polyp, Spigelman stage and patient's clinical conditions...

OBJECTIVE: We present the case of a 57-year-old man with a history of Roux-en-Y gastric bypass (RYGB) and colonic polyps who presented with an upper gastrointestinal obstruction based on massive stomach polyposis in the pouch. METHODS: Two months prior to this acute admission, he had undergone resection of the gastric remnant due to massive refractory intraluminal bleeding from a polypoid mass. Ten years earlier, right colectomy was performed due to hypertrophic polyposis unsuitable for endoscopic polypectomy...

Germline mutations in the gene encoding tumor suppressor kinase LKB1 lead to gastrointestinal tumorigenesis in Peutz-Jeghers syndrome (PJS) patients and mouse models; however, the cell types and signaling pathways underlying tumor formation are unknown. Here, we demonstrated that mesenchymal progenitor- or stromal fibroblast-specific deletion of Lkb1 results in fully penetrant polyposis in mice. Lineage tracing and immunohistochemical analyses revealed clonal expansion of Lkb1-deficient myofibroblast-like cell foci in the tumor stroma...

Background: In addition to the presence of neoplasia in the colon and rectum, patients with familial adenomatous polyposis (FAP) may develop numerous polyps and carcinoma within the upper gastrointestinal tract. Methods: The aim of the present paper was to review the incidence advanced duodenal polyposis or cancer and their surgical outcomes. A retrospective review of patients' records from our department was performed. Information was retrieved from a prospective collected data, including clinical (gender, age, family history), endoscopic [association with colorectal cancer (CRC), polyposis severity, age at diagnosis] and surgical management (age, time from the index surgery, type of procedure, morbidity)...

Gastric cancer and colorectal cancer are two common malignant tumors in digestive tract. 1% to 3% of gastric cancer and 5% to 15% of colorectal cancer are definitely hereditary cancer caused by germline gene mutation. Hereditary gastric cancer includes hereditary diffuse gastric cancer(HDGC) and hereditary intestinal gastric cancer (HIGC). CDH1 gene mutation is the main reason to cause HDGC, so the first degree and the second degree family members of HDGC patients are recommended to receive CDH1 mutation detection, endoscopic examination every year and undergo preventive total gastrectomy...

Inhibitors of the Wingless-related Integration site (WNT)/β-catenin pathway have recently been under consideration as potential chemopreventive agents against Familial Adenomatous Polyposis (FAP). This autosomal-dominant syndrome is caused by germline mutations in the gene coding for the protein APC and leads to hyperactivation of the WNT/β-catenin signaling pathway, uncontrolled intestinal cell proliferation and formation of adenocarcinomas. The aim of the present work was to: (i) test, on in vitro cultures of cells carrying FAP mutations and on ex vivo biopsies of FAP patients, the WNT inhibitory activity of extracts from two common southern Italian apples, Malus pumila Miller cv...

SCOPE: Evidence suggests that the dietary consumption of plant extracts containing polyphenols might help prevent the onset of cancers of the gastrointestinal tract. In the present study, the chemopreventive and antiproliferative efficacy of a grapevine shoot extract (Vineatrol(®) 30) containing resveratrol and resveratrol oligomers was investigated in vivo and in vitro. METHODS AND RESULTS: The in vivo study was performed using Apc(Min) mice on a high-fat diet, which represents a model of human adenomatous polyposis, while the potential of the extract as well as some of its isolated constituents to inhibit intestinal adenoma cell proliferation in vitro was investigated using APC10...

Cronkhite-Canada Syndrome (CCS) presents with gastrointestinal polyposis and the triad of cutaneous abnormalities including nail dystrophy, alopecia, and hyperpigmentation of the skin. The etiology is not well understood. The histology of skin lesion in CCS has not been routinely described. Especially, the nail matrix pathology has not been reported. In this study, the authors report the nail matrix pathology in a patient with CCS. Interestingly, the histologic evaluation revealed matrix hypergranulosis. Because matrix hypergranulosis is commonly found in several inflammatory nail diseases, this discovery points out that an inflammatory process is probably one of the important pathogeneses in CCS...

Stomach cancer rarely develops in patients with familial adenomatous polyposis (FAP), and Helicobacter pylori infection may increase the risk of FAP-related gastric cancer. We describe the case of a 64-year-old woman who developed multiple synchronous early gastric cancers without H. pylori infection. Nine cancer lesions were successfully treated by endoscopic submucosal dissection. An immunohistochemical analysis revealed that the tumors were positive for MUC2, MUC6, and CDX2, but negative for MUC5AC, suggesting that the tumors were gastrointestinal mixed type...

RATIONALE: Cronkhite-Canada Syndrome (CCS) is an idiopathic, nonhereditary syndrome haracterized by gastrointestinal (GI) polyposis and ectodermal changes including alopecia, onychatrophia, and pigmentation. CCS colon polyps were previously considered to be benign neoplasms. However, serrated adenoma was reported to be associated with malignant neoplasms in some cases of gastric and colorectal carcinomas, and esophageal cancers. Although malignant colon and gastric cancer have been reported in CCS, reports of distant metastasis have been rare in CCS...

BACKGROUND: Inflammatory myofibroblastic tumor (IMT) of the stomach is extremely rare in adults and exhibits a variable biological behavior that ranges from frequently benign lesions to more aggressive variants. Here we report a case of gastric IMT with lymph node metastasis in an adult who had undergone total colectomy for familial adenomatous polyposis (FAP). CASE PRESENTATION: A 37-year-old man presented gradual-onset epigastric discomfort; he had undergone total colectomy for FAP 6 years before...

Polyps of the gastrointestinal tract are very common lesions and most frequently sporadic in nature. Some polyp subtypes are associated with rare hereditary polyposis syndromes, including juvenile polyposis syndrome, Peutz-Jeghers syndrome, and Cowden syndrome. However, many sporadic benign lesions of the gastrointestinal tract can mimic some of these syndromic hamartomatous polyps. The role of the surgical pathologist is to raise the possibility of a hereditary condition in case of suggestive polyp histology and to look for clinical information to support the suspected diagnosis...

Peutz-Jeghers Syndrome (PJS) is an autosomal dominant hereditary polyposis syndrome. Clinical features include hamartomatous polyps, mucocutaneous pigmentation and an increased predisposition towards developing malignancy. Variants in STK11, a tumour suppressor gene, located on Chromosome 19, predispose to PJS. Peutz-Jeghers Syndrome is associated with increased rates of malignancy, particularly gastrointestinal. However, PJS is also associated with increased gynaecological, testicular and thyroid papillary malignancy...

Despite the small bowel comprising 90% of the mucosal surface area of the gastrointestinal tract, it is a rare site for neoplasia and only accounts for a little over 3% of the tumors that arise in the digestive tract. Benign small bowel lesions include lipomas, lymphangiomas, leiomyomas, neurofibromas, nodular lymphoid hyperplasia and adenomas, many of which are precursors to malignant lesions. Several polyposis syndromes are associated with small bowel polyps as well, including familial adenomatous polyposis syndrome, lynch syndrome, Peutz-Jeghers syndrome, Cowden syndrome and juvenile polyposis syndrome...

Gastric polyps include a wide spectrum of lesions with different histology and neoplastic potential. They are found in up to 6% of upper gastrointestinal endoscopy and are usually asymptomatic and incidentally diagnosed, being in the vast majority epithelial gastric polyps. Hyperplastic, fundic gland and adenomas are the most common types of gastric polyps and, although each type may have typical endoscopic appearances, they all must be sampled at the initial endoscopy for histological assessment. Also, the normal appearing gastric mucosa should be sampled to stage atrophic changes, rule out endoscopically non-visible dysplasia and to diagnose Helicobacter pylori...

Since 2001, small bowel capsule endoscopy (SBCE) has been widely implemented into clinical practice as a minimal-invasive diagnostic approach for diagnosing small bowel diseases. Currently, SBCE is moreover recognized as the first-line procedure for the diagnostic work-up of obscure gastrointestinal bleeding (OGIB) and for a variety of SB disorders including Crohn's disease, inherited polyposis syndromes, suspected small bowel tumors or refractory celiac disease [1,2]. In addition, capsule endoscopy is used to guide the decision whether device assisted enteroscopy (i...

Cronkhite-Canada syndrome (CCS) is a rare non-hereditary disease characterized by chronic diarrhea, diffuse intestinal polyposis and onychodystrophy. We present here a case of a middle-aged female who presented with chronic intermittent bloody diarrhea associated alopecia and loss of finger and toe nails. Labs were remarkable for microcytic anemia and severe hypoalbuminemia. Endoscopy showed numerous polyps scattered throughout the colon. She was treated with nutritional support and corticosteroid with complete resolution of her symptoms and endoscopic findings...
