Eosinophilic gastroenteritis with rectal involvement: case report and a review of literature.

An unusual case of eosinophilic gastroenteritis (EGE) is reported. Fewer than 150 cases of EGE have been reported in the world literature to date. This is the first case of this disease reported to have rectal involvement, and only the second case in which colonic involvement has been histologically documented. The addition of this case to those previously reported in the literature would suggest that EGE may involve any segment of the gastrointestinal tract.
