Diagnosis of eosinophilic gastroenteritis is easily missed

Figure 1 Endoscopic presentation of the eosinophilic gastroenteritis patients on gastroscopy. A: Mucosal edema and hyperemia of the greater curvature of stomach; B: Large sheet erosion in antrum; C: Pyloric stenosis with ulcers in duodenal bulba; D: Edema and hyperemia of the descending duodenum.

Figure 2 Endoscopic presentation of the eosinophilic gastroenteritis patients on colonoscopy. A: Mucosal edema and small hemorrhagic spot in the distal ileum; B: Mucosal edema and erosions in the transverse colon; C: Segmental erythemoid edema and hyperemia in the descending colon; D: Erythemoid edema and hyperemia in the sigmoid colon.

Figure 3 Pathology presentation of biopsy specimens from eosinophilic gastroenteritis patients (HE stain × 400). A: Massive infiltration of eosinophils in the gastric mucosa of an eosinophilic gastroenteritis (EGE) patient; B: Massive infiltration of eosinophils in the colonic mucosa of an EGE patient; C: Massive infiltration of eosinophils in the ascites fluid of an EGE patient.

Figure 4 Clinical and endoscopic presentation of eosinophilic gastroenteritis and non- eosinophilic gastroenteritis patients. No statistical significance was shown between eosinophilic gastroenteritis (EGE) and non-EGE patients in terms of clinical and endoscopic presentation (all P < 0.05).
