Erythema toxicum neonatorum typically resolves within what timeframe?

• A. 1-2 weeks
• B. 24-48 hours
• C. 3-5 days
• D. >1 month

Answer: (A)

Erythema toxicum neonatorum is a common, benign newborn eruption that appears soon after birth and goes away on its own. It typically resolves over about one to two weeks, sometimes a bit longer but rarely beyond a couple of weeks. This self-limited course is what makes the one-to-two-week timeframe the best fit. Shorter resolutions (like 24–48 hours) aren’t characteristic, and resolving after more than a month would raise concern for another condition. No treatment is needed for this rash.
