mantle cell lymphoma is an aggressive type of b-cell non-hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. the gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...

Abstract Introduction Most cases of colorectal cancer (CRC) occur sporadically; however, ∼ 3% to 6% all CRCs are related inherited syndromes, such as Lynch syndrome and familial adenomatous polyposis (FAP). The coli (APC) mutY DNA glycosylase (MUTYH) germline mutations the main genetic causes polyposis. Nevertheless, in many these genes have not been identified. aim present case report is descr...

The three autosomal dominant inherited polyposis syndromes, familial adenomatous polyposis, juvenile polyposis, and Peutz-Jeghers polyposis predispose to colorectal cancer as does hereditary non-polyposis colorectal cancer syndrome. Uncovering the genetic background of these four cancer traits provides the possibility for genetic testing of the family members of an affected patient. Before test...

Fundic gland polyps (FGPs) are the most common type of gastric polyps (up to 50%). They are found in up to 0.8-1.9 % of the general population, and in 40-84 % of the patients suffering from familial polyposis syndromes. They might be sporadic or associated to polyposis syndromes. When the former, they should be considered exclusively benign lesions, and possibly related to the chronic use of pr...

the inherited polyposis syndromes and colorectal carcinoma. Four patients are reported, to illustrate the wide spectrum of colonic polyps which may occur in multiple form in adults. Included are unusual cases of metaplastic and-juvenile polyposis. The subject is reviewed, and the need for accurate histological diagnosis is stressed. The possibility that the difference between familial adenomato...

BACKGROUND Serrated polyposis is a poorly understood and likely underdiagnosed condition. Little is known regarding the colorectal cancer risk, extracolonic phenotype, and cause of serrated polyposis. OBJECTIVE The aim of this study is to describe the clinical and family history features of a large cohort of individuals with serrated polyposis. DESIGN This is a retrospective cohort study fr...

Genetic Analysis of D-Loop Region Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study

INTRODUCTION Juvenile polyposis syndrome(JPS) is a rare autosomal dominant inherited condition. Hamartomatous polyps can affect the entire gastrointestinal tract but usually predominate in the colon. In this case report we present an unusual case of JPS that presented with massive gastric polyposis requiring a total gastrectomy. CASE PRESENTATION A 51-year-old man presented with symptoms of g...

We report a unique case of giant obstructing inflammatory polyposis associated with ulcerative colitis (UC). A 25-year-old Japanese man with an UC history of 2 years and 6 months was referred to our institution because of diarrhea and melena. His computed tomography scan showed marked dilation of the transverse and descending colon; therefore, we performed total colectomy. Macroscopic evaluatio...
