Key Takeaways
Pityriasis rosea is a common, benign, and self-limiting skin condition that primarily affects young adults. It is characterized by a rash that typically presents as a single, large, scaly, pink or red patch called the "herald patch" on the trunk, followed by the appearance of smaller, similar-appearing patches on the trunk, arms, and legs. Treatment for Pityriasis Rosea involves antihistamines, moisturizing creams and lotions, and mild topical corticosteroids to alleviate symptoms.
