Case of conventional/classic type of Erythema abigne (Eai) as a quiz. The diagnosis is straightforward with satisfying the diagnostic “H triad”: 1) history of cold weather, 2) heat source exposures-prolonged and or frequent, and 3) hyperpigmentation-reticulate dusky erythematous and confined to the exposed sites, then the diagnosis is outstanding, and a 4th H; confirmatory his topathological assay may be avoided.
