Sclerotic fibromas of the skin (SFSs) have a very characteristic histology but the clinical signs are non-specific. Consequently, it is extremely difficult to make a diagnosis of SFS on the basis of the clinical findings only. We report here two cases of SFS arising on the right scapular region and the right lower leg, respectively. Both cases were clinically similar to keloids. Skin surgeons should remember that SFSs are an important differential diagnosis from keloids.
