A school-age child with a pityriasis rosea rash asks about prognosis and management. Which action is appropriate first?

• A. Reassure the child's parents that the rash is benign and self-limited.
• B. Obtain a KOH preparation of a skin scraping to verify the diagnosis.
• C. Prescribe topical steroids to shorten the course.
• D. Recommend topical antihistamines and emollients to control itching.

Answer: (A)

Pityriasis rosea in children is a benign, self-limited eruption that typically resolves on its own over weeks. The best first step is to reassure the family that the rash will improve without aggressive treatment and that no invasive testing is usually needed if the presentation is classic. Diagnostic tests like a KOH prep won’t change management in a straightforward case. If itching is bothersome, use gentle skin care with emollients and, if needed, a non-sedating antihistamine; topical steroids may help itching briefly but do not shorten the course.
