Natal teeth are an infrequent occurrence at birth. Often these teeth are extracted because they are very mobile and pose a risk of aspiration. This is a rare case in which a natal tooth was extracted by the pediatrician with his fingers. A root fragment remained and out of this developed a large pulp polyp. This relationship has not been previously reported.

Colorectal cancer is the third most common cancer and the second most common cause of death from cancer in many industrialised countries. This disease will aVect 5% of the US population, resulting in over 130 000 new cases and 57 000 deaths projected this year. The age adjusted death rates are highly variable in populations located in diVerent parts of the world. For example, there are 3.4 case...

A 14 year old Malay boy with an adenocarcinoma of the transverse colon is reported. A lesion was discovered early when he presented with an uncommon complication in the form of a bowel intussusception. Emergency segmental colonic resection was performed, followed later by an extended left hemicolectomy following histological confirmation of the disease. Benign adenomatous polyp is believed to b...

Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Although, the underlying mechanism of carcinogenesis in gastric hyperplastic polyps is still uncertain, most malignant polyps are seen to originate from dysplastic epithelium rather than from hyperplastic epithelium. Herein, we report the case of a woman diagnosed with ...

Colonic lipomas with overlying adenomatous change are exceedingly rare with few reported cases.1, 2, 3 This is a case report of a 74 year old female who was found to have a polyp on the ileocaecal valve that was not amenable to endoscopic mucosal resection. The patient subsequently underwent a successful laparoscopic right hemicolectomy. The diagnosis of a submucosal lipoma with an overlying lo...

Background. Appropriate recommendations for a followup exam after an index colonoscopy are an important quality indicator. Lack of knowledge of polyp pathology at the time of colonoscopy may be one reason that followup recommendations are not made. Aim. To describe and compare the accuracy of followup recommendations made at colonoscopy based on the size and number of polyps with recommendation...

background: minimal bright red bleeding per rectum (mbrbpr) is a common complaint in adult patients. most studies have not been performed in patients with strictly minimal brbpr, and there are no evidence-based recommendations for this group of patients. materials and methods: patients with complaints as small amounts of red blood after wiping or a few drops of blood in the toilet bowl after de...

The adenomatous polyposis coli (APC) gene, whose mutations are responsible for familial adenomatous polyposis, is a major negative controller of the Wnt/beta-catenin pathway. To investigate the dose-dependent effects of APC protein in suppressing intestinal tumorigenesis, we constructed mutant mice carrying hypomorphic Apc alleles Apc(neoR) and Apc(neoF) whose expression levels were reduced to ...

Disturbances in DNA methylation are a characteristic of colorectal carcinogenesis. Folate-mediated one-carbon metabolism is essential for providing one-carbon groups for DNA methylation via DNA methyltransferases (DNMTs). Alcohol, a folate antagonist, could adversely affect one-carbon metabolism. In a case-control study of colorectal polyps, we evaluated three single nucleotide polymorphisms (-...
