🌿 Overview
Pityriasis rosea is a mildly itchy, self-limiting rash that occurs primarily in young adults. It begins with a single distinctive oval herald patch (¾ to 2½ inches in diameter) on the trunk that resembles ringworm. Three to ten days later, a wider eruption of smaller oval pink flat spots appears, spreading across the abdomen, along the thighs and upper arms, and up toward the neck in a characteristic 'Christmas tree' pattern. A scaly margin appears around the edges of patches after about a week. The condition is mild and usually clears completely in 6-8 weeks without treatment, and rarely recurs. The main reason to identify it is to distinguish it from psoriasis or eczema, which are more serious.

⚖️ Good to know
- Pityriasis rosea can look very similar to psoriasis, eczema, ringworm, or secondary syphilis.
- If the rash does not follow the classic pattern, does not clear within 8 weeks, or if there are other symptoms, see a physician to rule out these conditions.
- Secondary syphilis can produce a nearly identical rash and should not be missed.
