Eosinophilic Gastroenteritis in Tropical Area: about 6 Cases from Senegal

Abstract

The aetiologies of hypereosinophilia are dominated by digestive parasitosis and drug intake. In the tropics, because of the frequency of parasitosis, eosinophilic digestive pathologies of primary origin, which are rare, may be overlooked. We report 6 cases of eosinophilic gastroenteritis with polymorphic digestive manifestations testifying to the different locations of eosinophilic infiltration in the digestive parietal layer. Three patients had ascites rich in eosinophils, indicative of serous involvement, while the other two had a muscular form, and the last a mucosal involvement. The evolution was favourable in all cases with corticosteroid therapy, but a recurrence was noted in 4 cases when treatment was stopped.
