RESUMEN
Cold urticaria and cholinergic urticaria are considered to be distinct disorders in which mediator release and hives can be induced by different stimuli. Cold urticaria can be induced by cold stimuli, and cholinergic urticaria, characterized by micropapular wheals, by exercise, emotional stimuli, or other stresses that increase the body temperature. While neither cold urticaria nor cholinergic urticaira is rare, it is unusual to see both disorders occurring in the same patient. Also, our case presents atypical urtication to cold exposure, similar to classic cholinergic urticarial lesions, called "cold-induced cholinergic urticaria". We present a 20-year-old man with 4-year history who experienced generalized micropapular wheals induced by cold exposure as well as exercise and hot environment.
