Diagnostic Considerations

Although the diagnosis of striae is usually straightforward, the rare possibility of Cushing syndrome must be entertained. In the latter, striae are characterized by their inordinate breadth, depth, and intense color.

In linear focal elastosis (elastotic striae), asymptomatic, yellow linear bands arrange themselves horizontally over the lower back. These lesions may resemble striae distensae, but they are palpable rather than depressed and yellow rather than purplish or white.
