Enteritis cystica profunda causing ileoileal intussusception in a child.

Enteritis cystica profunda (ECP) is an exceedingly rare lesion of the small intestine. It has identical histopathologic features as colitis cystica profunda, which is mainly a disease of adults and a rare benign lesion of the distal colon and rectum of uncertain cause. Only 12 cases of ECP with only one pediatric case, have been reported in English-language medical literature. Here the authors present the second pediatric case of ECP with the literature review and discussion of the etiology.
