INTRODUCTION: Mantle cell lymphoma (MCL) is a subtype of non-Hodgkin B-cell lymphoma, accounting for 6% of all non-Hodgkin lymphoma. The typical appearance of intestinal MCL is multiple lymphomatous polyposis, whereas presentation as protruding lesions is uncommon. We herein report the case of a 64-year-old male patient who was admitted to our hospital with epigastric pains. On endoscopy, submucosal neoplasma were identified in the gastric antrum, the duodenal bulb, and the rectum. On endoscopic ultrasonography (EUS) (OLYMPUS EUS EU-ME2, Miniprobe sonography), the lesions were homogeneously hypoechoic and originated from the submucous layer or muscularis mucosa...

Lower gastrointestinal (GI) neuroendocrine neoplasms (NENs) of the colon and rectum are uncommon and not traditionally associated with hereditary GI cancer syndromes. However, with widespread implementation of colorectal cancer screening programs, lower GI NENs are being identified with increasing frequency. We report the first case series of six patients with lower GI NENs who were diagnosed with hereditary GI cancer syndromes by germline testing. Two patients presented with poorly differentiated rectal neuroendocrine carcinoma (NECs) with colonic polyposis and were found to have Familial Adenomatous Polyposis and MYH-Associated Polyposis, respectively...

Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP...

Introduction Restorative proctocolectomy (RP) is undertaken for patients with familial adenomatous polyposis (FAP) and ulcerative colitis, but is associated with a risk of anastomotic leak. Case history A 20-year-old male with a family history of FAP had a RP with a double-stapled J-pouch and covering loop ileostomy. At ileostomy reversal 21 months later, he presented with significant anal bleeding. He proceeded to theatre for endoscopy. Pouchoscopy showed a pouch full of blood and a foreign object trapped in a diverticulum...

Peutz-Jeghers syndrome (PJS) is a rare, autosomal dominant inherited disorder, caused by germline mutations in the LKB1 tumour suppressor gene. It is clinically characterised by distinct perioral mucocutaneous pigmentations, gastrointestinal polyposis and an increased cancer risk in adult life. Hamartomatous polyps can develop already in the first decade of life and may cause various complications, including abdominal pain, bleeding, anaemia, and acute intestinal obstruction. Furthermore, patients have an increased risk for developing cancer, both in the gastrointestinal tract as in other organs...

Endoscopic submucosal dissection (ESD) may remove gastrointestinal neoplasias even associated with severe fibrosis [1-3]. We report the first case of ESD for a large neoplasia located in the remnant rectum after total colectomy in a patient with familial adenomatous polyposis (FAP). A 19 year old female with FAP underwent total colectomy with ileorectal anastomosis (IRA). Fourteen years later a surveillance endoscopy revealed a 0-Is+IIa lesion, measuring 75mm, occupying the "dog ear" portion of the rectum and involving the IRA (fig 1a-b)...

BACKGROUND & AIMS: Video capsule endoscopy (CE) provides a noninvasive option to assess the small intestine, but its use with respect to endoscopic procedures and cross-sectional imaging varies widely. The aim of this consensus was to provide guidance on the appropriate use of CE in clinical practice. METHODS: A systematic literature search identified studies on the use of CE in patients with Crohn's disease, celiac disease, gastrointestinal bleeding, and anemia...

Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body...

Cronkhite-Canada syndrome is an acquired inflammatory polyposis syndrome in which alopecia, onychomadesis and hyperpigmentation occur concurrently with gastrointestinal symptoms. The pathophysiology of alopecia in Cronkhite-Canada Syndrome has not been definitively elucidated and we present evidence for alopecia incognita as a possible mechanism of hair loss.

AIMS: Massive gastric polyposis is a rare entity often associated with juvenile polyposis syndrome (JPS). We evaluated the clinicopathologic features of 22 patients with abundant gastric juvenile-type or hyperplastic-like polyps. METHODS AND RESULTS: The study included 12 males and 10 females with a median age of 48 years (range: 13-79). Fourteen (64%) patients carried a diagnosis of JPS, and three had prior gastrointestinal adenocarcinomas. Patients without known JPS presented at an older median age (60 versus 40 years; P=0...

BACKGROUND: Colorectal cancer is the second most common cause of cancer deaths for both men and women, and the third most common cause of cancer in the U.S. Toxicity of current chemotherapeutic agents for colorectal cancer, and emergence of drug resistance underscore the need to develop new, potentially less toxic alternatives. Our recent cross-sectional study in a large Appalachian population, showed a strong, inverse, dose-response association of serum perfluorooctane sulfonate (PFOS) levels to prevalent colorectal cancer, suggesting PFOS may have therapeutic potential in the prevention and/or treatment of colorectal cancer...

Multiple lymphomatous polyposis (MLP) as an extranodal manifestation of mantle cell lymphoma (MCL) in the gastrointestinal tract is rare and not often reported in the literature. We describe the case of a 63-year-old female with asymptomatic MLP found during staging bidirectional endoscopy of MCL. The patient presented only with dyspnea, but was found on physical exam to have diffuse lymphadenopathy, and subsequent positron emission tomography (PET) CT showed extensive lymph node adenopathy consistent with lymphoma...

The LKB1 tumor suppressor was identified in 1998 as the gene mutated in the Peutz-Jeghers Syndrome (PJS), a hereditary cancer predisposition characterized by gastrointestinal polyposis and a high incidence of cancers, particularly carcinomas, at a variety of anatomic sites including the gastrointestinal tract, lung, and female reproductive tract. Women with PJS have a high incidence of carcinomas of the uterine corpus (endometrium) and cervix. The LKB1 gene is also somatically mutated in human cancers arising at these sites...

PURPOSE: Desmoid tumor (DT) is a rare myofibroblastic proliferative neoplasm, but can occur in up to 26% of patients with familial adenomatous polyposis (FAP). Therefore, DT may be an extraintestinal manifestation of FAP that precedes the development of advanced malignancies. The aim of this study was to identify the incidence of polyps in DT patients and investigate value of colonoscopy for diagnosis of FAP in DT patients without gastrointestinal symptoms. MATERIALS AND METHODS: The records of patients diagnosed with DT were retrospectively reviewed using the clinical data warehouse (CDW) system...

BACKGROUND: In a large number of patients with multiple gastrointestinal adenomatous polyps, no causal germline mutation can be found. Non-genetic factors may contribute to the development of adenomatous polyps in these unexplained polyposis patients. In the development of gastrointestinal cancer, prior exposure to abdominal radiotherapy has been identified as such a factor, as it increases the gastrointestinal cancer risk in cancer survivors. A relationship of radiotherapy with intestinal polyposis, however, has not yet been described...

A 45-year-old male with a prosthetic aortic valve presented to the hospital with several months of generalized malaise. On admission, he was noted to have anemia of unclear etiology and subsequently became febrile with multiple blood cultures growing Lactococcus garvieae. Inpatient workup was concerning for infectious endocarditis (IE) secondary to Lactococcus. The patient was discharged home with appropriate antimicrobial therapy; however, he was readmitted for persistent, symptomatic anemia and underwent colonoscopy, which revealed innumerable colonic polyps consistent with Familial Adenomatous Polyposis (FAP) that was later confirmed with genetic testing...
