Classic clinical finding of Fifth disease?

• A. Koplik spots on mucosa
• B. Bull's eye rash
• C. Vesicular rash on hands
• D. Slapped face rash on cheeks

Answer: (D)

Fifth disease, or erythema infectiosum, is classically identified by a bright red, "slapped-cheek" facial rash. This distinctive facial flush is often followed a day or two later by a lace-like, reticular rash that appears on the trunk and limbs. This pattern is the hallmark that helps distinguish it from other pediatric rashes, such as measles (which shows Koplik spots), Lyme disease (a bull’s-eye rash), or hand-foot-and-mouth disease (vesicular lesions on hands and mouth). The presentation is usually mild in children, with supportive care being the main approach; infection during pregnancy can have serious fetal implications, so pregnant women are advised to avoid exposure.
