“Allergic” gastroenteritis; Eosinophilic gastroenteritis
Eosinophilic gastritis is characterized by a prominent eosinophil-rich inflammation in the gastric wall (Lash et al. 2009) without known cause. Isolated gastric eosinophilia is very rare and it is usually associated with involvement of the duodenum, esophagus, or other gastrointestinal (GI) segments, which is also referred as eosinophilic gastroenteritis (Lash et al. 2009).
As the gastric mucosa has a variable number of eosinophils, the diagnosis, especially in biopsy material, can be difficult. One study addressed the number of eosinophil counts in the normal gastric mucosa and other eosinophil-rich entities in the stomach and the authors proposed working diagnostic criteria: (1) patients who have gastric biopsies that show an average density of >127 eosinophils/mm2(or ≥30 eosinophils per HPF in microscopes equipped with wide-lens oculars) and (2) patients that have no known associated causes of...
