Pediatric rectal Dieulafoy's lesion.

Dieulafoy's lesions are an unusual cause of gastrointestinal hemorrhage. The overwhelming majority of lesions are found in the upper gastrointestinal tract, particularly along the lesser curvature of the stomach in the region supplied by the left gastric artery. Rectal Dieulafoy's lesions have never before been reported in the pediatric population, and our case represents only the third reported occurrence of a rectal Dieulafoy's lesion in the English medical literature. Successful treatment was administered, i.e., the combination of sclerotherapy followed by thermocoagulation. We therefore recommend that rectal Dieulafoy's lesion be included in the differential diagnosis of children with severe rectal bleeding and that management follow the same principles used to treat upper gastrointestinal tract Dieulafoy's lesions: injection therapy followed by heater probe coagulation.
