Conclusion: Localized gastric amyloidosis, being rare in incidence, should be considered in the differentiation of gastric tumors, in which biopsy is the only means to confirm the diagnosis.

In this study, we investigated the clinical characteristics, endoscopic appearances, and treatments for patients with EoE. Methods: Three patients with EoE (3 women; mean age, 27.3 years) were diagnosed with EoE based on typical symptoms, endoscopic abnormalities and infiltration of the esophageal epithelium with >15 eosinophils/high-power field. The average endoscopic follow-up period was 19.2 months. Results: Two patients had dysphagia symptoms and 1 patitent had epigastralgia symptoms, which not improved in 3 patients who were treated with proton pump inhibitor. Three patients

had the history of the allergy disease of asthma, atopic dermatitis, and a food allergy. The endoscopic features were linear furrows in 2 patients, and was white papules in 1 patient. CX-5461 chemical structure Three patients had a mean peak eosinophil count of 94.7 eos/hpf in the esophageal biopsy specimens.

All the patients had an average of 9.13% of peripheral eosinophilia. All the patients were given with the corticosteroid administration of 30 mg of introduction, and the quantity of it was decreased gradually. As a result, the improvement of symptoms and endoscopic Ribociclib price features had in all the patients. However, the one patient was permitted recurrence of symptom when corticosteroid was 5 mg. Conclusion: Endoscopic features of EOE is should be known. New evidence from ongoing research on EoE should thus seek to define a common treatment algorithm to optimize EoE patient management.
