ABSTRACT
A 2-month-old baby girl, born at term by spontaneous vaginal delivery after an uneventful pregnancy, is transferred from a community hospital for investigation of hematemesis. She presented 3 days previously to the referring hospital with significant stridor. A diagnosis of croup was made and she was placed on systemic intravenous steroids, with minimal improvement. On the third hospital stay, she had two episodes of bright red emesis, corresponding to a drop in Hgb from 10.5 mg/dL to 8 mg/dL and new onset tachycardia.
