Synopsis

Linear focal elastosis (LFE), also known as elastotic striae, is an abnormality of elastic tissue that presents with palpable, indurated, or atrophic linear plaques that have a yellowish hue. Lesions are asymptomatic and tend to develop on the middle or lower back, thighs, arms, and breasts. It is not uncommon for lesions of LFE to occur in association with striae distensae.

This condition predominates in males, usually in elderly males, on their backs. However, more recent reports of cases occurring in younger individuals point to the possibility that LFE is more common in younger populations than previously thought.

The pathogenesis of LFE is unknown. Various theories have been proposed, including that LFE represents a degenerative or regenerative process of striae distensae or that the condition may represent a nevoid or hamartomatous condition of degenerative or regenerative processes occurring in elastic fibers.
