Inflammatory fibroid polyps in children: A new case report and a systematic review of the pediatric literature.

Aim: To study that inflammatory fibroid polyps (IFPs) in children are extremely uncommon tumors that may occur throughout the gastrointestinal tract.

Methods: A systematic review of the pediatric literature and a report of a new case of IFP is also presented. The PubMed database was searched for original studies on pediatric IFPs since 1960, according to "Preferred reporting items for systematic reviews and meta-analyses" guidelines for systematic reviews.

HER-2 overexpression/amplification in Barrett's oesophagus predicts early transition from dysplasia to adenocarcinoma: a clinico-pathologic study.

Barrett's oesophagus (BO) is the primary precursor lesion for oesophageal adenocarcinoma (ADC). The natural history of metaplasia-dysplasia-carcinoma sequence remains largely unknown. HER2/neu oncogene results overexpressed/amplified in preneoplastic lesions and in ADC of the oesophagus and it has been associated with poor prognosis.

Immunocytochemical assessment of p53 protein to detect malignancy in increased cell-yield brush cytology from the biliopancreatic tree.

Background: Malignancies arising from the biliopancreatic tree are often diagnostic challenges for the gastroenterologist and the pathologist, especially when strictures without masses are present.

Aim: To evaluate the diagnostic yield of p53 immunocytology for the detection of malignancies in material obtained by biliopancreatic tree brushing by means of an increased cell-yield procedure.

Patients And Methods: Cytologic specimens obtained from biliary and pancreatic tree brushing in 24 patients with biliary strictures suspected for malignancy were assessed by conventional Papanicolau staining and p53 immunocytochemistry.

The pathology of gastric cardia: a prospective, endoscopic, and morphologic study.

"Carditis" (inflammation of the gastric cardiac mucosa) may be associated with gastroesophageal reflux disease (GERD), whereas other studies argue that Helicobacter pylori could play a significant role in the chronic cardiac damage. We examined prospectively histologic features of gastric cardia, esophagitis, and H. pylori status in 204 consecutive subjects with GERD symptoms (57.
