Kyrle disease is an uncommon disorder that affects individuals with diabetes and end-stage renal disease. Age of onset is between 30 and 50 years, and the majority of cases occur in women. It is classified as a reactive perforating collagenosis; related disorders include elastosis perforans serpiginous and perforating folliculitis.1 The etiology is uncertain, although it is postulated that chronic pruritus in predisposed patients induces rupture of collagen fibers with consequent elimination.2
Kyrle disease is characterized by crops of papules and nodules on the legs and, to a lesser extent, on the arms and trunk. Individual lesions are deep red in color and contain a characteristic keratin plug. Less severe cases may improve with topical retinoic acid.3 Oral retinoids and ultraviolet therapy have proven of value in more extensive cases.1,4
