Can you guess what this rash is? 👀
This classic presentation is pityriasis rosea, a condition I actually love teaching about because once you know it—you’ll never forget it. It often starts with a single “herald patch,” then spreads in a Christmas tree pattern across the trunk.
It commonly affects young, healthy patients and is likely triggered by a viral reactivation. While it can look alarming, it’s usually self-limited and resolves on its own over weeks to months.
Moisturizing, avoiding fragrance, mild sun exposure, and topical steroids can help with symptoms—but it’s important to get checked, because other conditions like ringworm, psoriasis, or even syphilis can look similar.
If you have a widespread or unexplained rash, don’t guess—come see your dermatologist.
