Polle syndrome: chronic diarrhea in Munchausen's child.

A child with a complex history of chronic diarrhea and a seizure disorder, with multiple nondiagnostic previous evaluations, is presented. Under careful observation and with minimal diagnostic studies, the source of this child's chronic disorder was confirmed to be exogenous drug administration by the mother. Polle syndrome, a child-abuse variant of Munchausen syndrome, must be considered as part of an aberrant family social setting by adult or pediatric physicians who uncover a chronic factitious disease. More attention to psychosocial history gathering may preclude well-meaning, but unwarranted, multiple diagnostic endeavors.
