Progressive pigmentary purpura.
A 58-year-old man presented for evaluation and treatment of non-tender, non-pruritic, annular patches on the right temple and frontal aspect of the scalp that reddened with exercise. A biopsy specimen showed a purpuric dermatitis with features of lymphocytic vasculitis; a diagnosis of exercise-induced progressive pigmentary purpura was made. Whereas progressive pigmentary purpura is purported to be caused by exercise, other similar appearing entities are associated with exercise, namely exercise-induced vasculitis (EIV). EIV may be considered as an acute microcirculatory deficiency and thermoregulation decompensation that occurs after episodes of exhaustive major muscular activity or after unusual or excessive exercise. The combination of age greater than 50 years, heat, and prolonged exercise are the most potent contributing factors. This is the first report of exercise-induced progressive pigmentary purpura.
