STRIAE RUBRAE: CUSHING’S SYNDROME

Abstract

Striae rubrae or red striae are found in different circumstances like pregnancy, weight gain and Cushing’s syndrome regardless of endogenous or exogenous type. This type of skin lesion is commonly found in general population and usually does not underline a severe condition. The histological aspect that involves the stretch marks is the destruction of the dermal fibbers and their local network. The fibbers have receptors for glucocorticoids. A secondary epidermal anomaly is also seen. In benign scenarios the prevention with topic applications is still a matter of debate while therapy lasers of different types might help. In cases with pathological glucocorticoids excess the removal of the source improves the skin lesions yet not completely, they become white. We aim to introduce two cases of Cushing’s disease of different origins to whom impressive red striae were positive from the presentation. Red striae may be the hallmark of Cushing’s syndrome in association with different cardio-metabolic and/or bone complications. Despite the remission of the glucocorticoid excess the skin lesions are not completely reversible.
