Eosinophilic gastroenteritis in an adolescent male with history of chronic bullous disease

Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract. Although commonly associated with allergic diseases, it is also rarely associated with autoimmune disorders. This case report describes a 17-year-old Filipino male with eosinophilic gastroenteritis, manifesting as abdominal pain, vomiting and diarrhoea. He had no allergic diseases, but he was previously diagnosed with chronic bullous disease. His symptoms improved with the initiation of corticosteroids. To date, this is the first case report of a patient with eosinophilic gastroenteritis and chronic bullous disease.
