To the Editor.—  Recently, an article entitled "Scleredema and paraproteinemia: Enhanced collagen production and elevated type I procollagen messenger RNA level in fibroblasts grown from cultures from the fibrotic skin of a patient" by Oikarinen et al was published in the Archives.1 The same patient that was in this study was also included in another study by Ohta et al2 that was published in the Journal of the American Academy of Dermatology this January.
