Yellow Urticaria in a Patient with Liver Disease

Abstract

Background: Yellow urticaria is a rarely reported phenomena that occurs in patients with hyperbilirubinemia that suffer an episode of urticarial rash. A variety of insidious etiologies of hyperbilirubinemia have been reported in cases of yellow urticaria making it an opportunity to catch serious liver or biliary disease early in its course. Case Report: We report a case of yellow urticaria that occurred in a 67-year-old male suffering from end-stage liver disease after he had received a transfusion of fresh frozen plasma. Physical examination and thorough history collection allowed the determination of the proper diagnosis and guided further clinical care. Conclusion: An occurrence of yellow urticaria necessitates that the clinician finds two diagnoses: the cause of hyperbilirubinemia, and the cause of urticaria. While striking in appearance, yellow urticaria may be most clinically significant when it prompts recognition of previously unknown hepatic or biliary pathology.
