Aim: To assess the risk of colonic polyps, adenomas and advanced neoplastic lesions (ANL) in patients with sporadic gastric polyps, especially those with fundic gland polyps (FGP).
Methods: Clinical records of patients who had performed an upper and a lower digestive endoscopy between September 2007 and August 2008 were retrospectively analyzed. A case-control study was carried out, calling patients with gastric polyps as "cases" and patients without gastric polyps as "controls". The risk of colonic polyps, adenomas and ANL (villous component ≥ 25%, size ≥ 10 mm, or high grade dysplasia) was assessed [odds ratio (OR) and its corresponding 95%CI].
Results: Two hundred and forty seven patients were analyzed: 78 with gastric polyps (cases) and 169 without gastric polyps (controls). Among the cases, the majority of gastric polyps were FGP (80%, CI: 69-88) and hyperplastic (20%, CI: 12-31); 25% had colonic polyps (25% hyperplastic and 68% adenomas, from which 45% were ANL). Among the controls, 20% had colonic polyps (31% hyperplastic and 63% adenomas, from which 41% were ANL). The patients with sporadic FGP had an OR of 1.56 (CI: 0.80-3.04) for colonic polyps, an OR of 1.78 (CI: 0.82-3.84) for colonic adenomas, and an OR of 0.80 (CI: 0.21-2.98) for ANL. Similar results were found in patients with gastric polyps in general.
Conclusion: The results of this study did not show more risk of colorectal adenomas or ANL neither in patients with sporadic gastric polyps nor in those with FGP.

Peutz-Jeghar syndrome (PJS) is an inherited condition that puts people at an increased risk for developing hamarotmatous polyps in the digestive tract as well as cancers of the breast, colon, rectum, pancreas, stomach, testicles, ovaries, lung and cervix. With typical presentation, majority cases of PJS can be diagnosed in childhood. PJS is inherited by mutation in the STK II gene, also known as LKB1 gene.

Background: Familial adenomatous polyposis (FAP) is an autosomal dominant colorectal tumour syndrome characterised by the formation of multiple adenomatous polyps throughout the colon. It is important to understand the extracolonic phenotype that characterizes FAP. Most previous case reports of patients with both FAP and intellectual disability (ID) have described deletions in all or part of chromosome 5q, including the APC locus.

Objectives: Patients with Peutz-Jeghers syndrome (PJS) require continuous medical management throughout their lives. However, few case series regarding the clinical course, polyp surveillance, and treatment, including endoscopic ischemic polypectomy (EIP) for pediatric patients with PJS, were reported. We analyzed the current status and clinical course of pediatric patients with PJS under the management of our institute, including those treated with EIP.

The rare gastrointestinal tract epithelial polyp known as a pyloric gland adenoma (PGA) is more common in elderly women and uncommon in the duodenum. There are reports of two PGA cases involving high-grade intraepithelial neoplasia. A 75-year-old man was admitted to the hospital as Patient 1 due to "epigastric distension and pain for more than 10 days".

In this study, we present a case of a 51-year-old man with a gastric lesion initially suspected to be early gastric cancer but was ultimately diagnosed as a Gastric cystic polyp (GCP). The patient underwent diagnostic endoscopic submucosal dissection (ESD) based on the lesion's appearance and characteristics. Detailed pathological and immunohistochemical analysis confirmed the diagnosis of GCP.
