Urticaria is a prevalent inflammatory dermatological condition with a global estimated lifetime prevalence of up to 20%. Yellow urticaria is not a distinct medical condition; rather, it refers to the manifestation of yellow-colored wheals that appear in certain individuals with elevated serum bilirubin levels. This excess bilirubin accumulates in various tissues, including the conjunctiva and skin. The occurrence of yellow urticaria is notably rare and uncommon. In this report, we present a case of yellow-colored urticaria in a patient diagnosed with obstructive biliary stones, complemented by a concise review of previously documented cases in the literature.
