Striae gravidarum

Abstract 

Striae are atrophic linear plaques, most often found on the breasts, abdomen, hips, and thighs. They develop in a variety of circumstances, some of which involve physical stretching of the skin, such as adolescent growth spurts, and during hormonal changes, such as Cushing's syndrome. It has been suggested that genetics may play a role in their development. Regardless of the etiology, all striae display the same histological changes in the dermis showing atrophy and loss of rete ridges. These findings are similar to those seen with scar formation. At present, no definitive treatments have been established.
