Acne that appears at which age should prompt detailed endocrine laboratory testing for possible underlying systemic disease?

• A. 13-15
• B. 8-12
• C. 16-18
• D. 5

Answer: (D)

Early-onset acne in a child is a red flag for an underlying endocrine or systemic condition. When acne appears around 5 years of age, it is far prepubertal and not typical benign acne of childhood; this prompts considering androgen excess or other systemic causes. In contrast, acne beginning around the expected pubertal years (roughly ages 8–12 or 13–18) is commonly puberty-driven and usually does not require extensive endocrine testing. If a child has acne at age 5, the evaluation would typically include endocrine laboratory testing to look for sources of excess androgens or other hormonal derangements, such as congenital adrenal hyperplasia, adrenal or gonadal tumors, or signs of early puberty or Cushing syndrome. This is why the age 5 scenario is the one that should prompt detailed endocrine workup.
