title: Episodic gross hematuria in association with allergy symptoms in a child.
abstract: BACKGROUND
  A relationship between allergy and the development of various renal diseases has been postulated, but never proven.
  
  
  METHODS
  We present the case of a child with idiopathic episodic gross hematuria. The child also has significant environmental allergies, and his episodes of hematuria coincide with flares of his allergic symptoms. The available literature on hematuria and allergy was reviewed in order to further explore the potential role that allergy may play in the pathogenesis of genitourinary tract disease.
  
  
  CONCLUSIONS
  This case, as well as others reported in the literature, suggest that allergy should be considered as a possible diagnosis in children with otherwise unexplained hematuria.
