eosinophilic gastritis presenting as tissue necrosis

Eosinophilic gastroenteritis is very rare disorder that is characterized by eosinophilic infiltration of the gastrointestinal tract in the absence of any definite causes of eosinophilia. It is associated with various clinical gastrointestinal manifestations, and depends on the involved layer and site. We report a case of eosinophilic gastritis presenting with severe necrosis. The symptoms disappeared immediately after beginning steroid treatment, and the eosinophil count decreased to the reference range. The patient showed eosinophilic gastritis characterized by necrotic change such as necrotizing gastritis. It is a unique presentation of eosinophilic gastritis. To the best of our knowledge, no case of eosinophilic gastritis characterized by necrotic change such as necrotizing gastritis has been previously reported in Korea.
