OverviewStriae in the popliteal fossa: Striae or stretch marks result from stretching of the skin, or other influences such as Cushing's syndrome. Most pregnant women experience striae at some point during their pregnancy. This picture shows striae in the popliteal fossa (the area on the back side of the leg at the knee joint). When the striae first appear they have a violaceous (red-purple) color, but over time they take-on a dull white appearance.
