Two cases of linear focal elastosis (elastotic striae).

Linear focal elastosis (LFE) or elastotic striae was first described by Burket in 1989 in three elderly men. They presented with striae-like yellow palpable bands on their backs. Burket described many fine wavy bundles of elastic fibers separating the collagen in the middle to reticular dermis under microscopic examination. Until recently, there have been about 14 reported cases of LFE; elderly males are predominant. We encountered two Korean teen-aged males with linear, reddish, palpable bands and some atrophic bands across their backs. Histopathological examination revealed that elastosis was not as prominent as in previously reported cases. Our cases might represent early-evolving LFE.
