Eosinophilic Gastroenteritis and Familial Mediterranean Fever in a Child With MEFV Gene Mutation

Eosinophilic gastroenteritis (EG) is a rare inflammatory disorder affecting both children and adults. The exact etiology of the disease is not clear. A child presented with episodic generalized abdominal pain since a year ago without fever at first. After endoscopic and colonoscopic examinations, histopathological examination showed an increased number of eosinophils and diagnosis of EG was made. After elimination of dairy products from his regimen, abdominal pain attacks was reduced, but he got a fever. Familial Mediterranean Fever (FMF) diagnosis was made by genetic evaluation which showed MEV gene mutation. Symptoms were resolved with the treatment of colchicine which confirmed FMF diagnosis.
