"Dewdrops on a rose petal" is a classic description of lesions associated with which condition?

The phrase "dewdrops on a rose petal" vividly describes the appearance of the lesions associated with varicella, also known as chickenpox. This condition typically presents with a characteristic vesicular rash that includes small, fluid-filled blisters (vesicles) that look like dewdrops resting on a smooth skin surface. These vesicles often appear in crops, evolving from macules to papules and finally to vesicles, which can break and form crusts.

In contrast, herpes simplex and shingles lesions can also present with vesicles, but they are not described using the same imagery. Herpes simplex typically leads to grouped vesicles on an erythematous base that are more clustered and may ulcerate, while shingles (or herpes zoster) usually presents in a dermatomal distribution with vesicles that can also develop into crusts but lacks the "rose petal" description. Impetigo, primarily a bacterial skin infection, shows honey-colored crusts and does not exhibit vesicles resembling dewdrops.

Therefore, the associated description of lesions clearly aligns with varicella, making it the correct choice.
