GlossaryPityriasis Rosea

common skin rash with a herald patch and Christmas tree pattern

Pityriasis Rosea is a common skin condition that typically starts with a single, large, pink, scaly patch known as a "herald patch," followed by smaller patches that spread across the body in a Christmas tree pattern. It is believed to be caused by a viral infection and usually resolves on its own within 6 to 8 weeks, though it can cause itching and discomfort.
