Which skin finding is a sign of Cushings syndrome in children?

Explanation:
Excess cortisol weakens and thins the skin by breaking down collagen, leading to tearing and formation of wide, purple-streaked stretch marks. These violaceous striae are a classic skin finding in Cushing’s syndrome, often seen on the abdomen, hips, and thighs. The other features—moon face and buffalo hump—are due to fat redistribution rather than skin texture, and short stature reflects growth suppression rather than a skin change. So the purple stretch marks best reflect the skin involvement from cortisol excess.
