We present a case of congenital juvenile xanthogranuloma (JXG) with both cutaneous and renal involvement. Skin lesions consisted of bluish papules and nodules (blueberry muffin baby) located on the head, trunk and proximal extremities. Subsequent investigations revealed a renal mass. Histopathology of both cutaneous and renal specimens was consistent with JXG. Both clinical presentation and extracutaneous localization were remarkable.
