Near fatal eosinophilic gastroenteritis responding to oral sodium chromoglycate.

Eosinophilic gastroenteritis (EG) is an uncommon disorder, characterised by cramping abdominal pain, diarrhoea and vomiting and histologically by eosinophilic infiltration of bowel wall. We present a patient who developed EG during the course of a systemic, necrotising vasculitis, who became critically ill after failure of treatment with corticosteroids and cytotoxic drugs and responded only to oral sodium chromoglycate.
