Describe the rash associated with measles.

• A. Erythematous, maculopapular, blanching rash that begins on the face and spreads cephalocaudally.
• B. Vesicular rash starting on the trunk.
• C. Papular rash limited to the face.
• D. Pustular rash on the extremities.

Answer: (A)

Measles produces an erythematous, maculopapular rash that blanches with pressure. It follows a classic cephalocaudal progression, starting on the face (often around the hairline or behind the ears) and spreading downward to the trunk and then the limbs over a couple of days. The blanching indicates superficial vasodilation in the skin, which is typical for this exanthem. This pattern helps distinguish it from rashes that are vesicular (like chickenpox, which starts on the trunk), papularOnly on the face (not characteristic of measles), or pustular on the extremities (which points to other conditions).
