Which of the following is a common skin finding in patients with Cushing's syndrome?

In patients with Cushing's syndrome, striae, often referred to as "stretch marks," are a well-known skin finding. These striae typically appear as purplish or reddish streaks on the skin, particularly on areas such as the abdomen, thighs, breasts, and arms. This skin change occurs as a result of the increased level of cortisol, which leads to skin thinning and loss of elasticity.

In the context of Cushing's syndrome, elevated cortisol levels can lead to rapid weight gain and changes in skin texture, contributing to the development of these prominent striae. The presence of these stretch marks is a key indicator in diagnosing and managing this endocrine disorder. Other skin findings might occur, but striae are particularly characteristic and serve as a significant clinical clue during evaluation.
