Abstract

Linear focal elastosis (LFE) is characterized by several asymptomatic, yellow, palpable, irregularly indurated, striae-like lines extending horizontally across the middle and lower back. A focal increase in elastic fibers is a hallmark of the disease as seen from biopsy specimens. The pathogenesis of LFE is unclear, as is the association between LFE and striae distensae (SD). However, the prevailing opinion is that LFE represents an excessive regenerative process of elastic fibers and is analogous to keloidal repair of SD. Although the timing of onset of LFE and SD was not synchronous in our patient, the triggering factor was the same, which was the growth spurt. This case is supporting the putative association between LFE and SD.
