Hematuria due to Cow Milk Allergy: a case report

Background: Cow milk allergy is one of the most common food allergies in young children causing a wide range of clinical syndromes due to immunologic responses to cow milk proteins. In this report we introduce an infant with dietary protein proctitis due to a cow’s milk referred with hematuria and bloody stool. Case Presentation: Our case was a 10- month old male infant with hematuria and bloody stool following consumption of yogurt. The infant had prior history of blood in stool at 20th day and 2nd month of life while exclusively breastfed. The episodes of bloody stool had been resolved at the time with elimination of cow milk dairy products form the mother’s diet. All physical examinations and laboratory tests were normal and with stopping Bovine products, the symptoms were disappeared. Conclusion: Allergy should be considered as a probable diagnosis in children with otherwise unexplained hematuria
