Christmas Tree Rash (Pityriasis Rosea)

Believed to be triggered by a viral infection. It typically begins with a single large 'herald patch'.

Because the exact cause is unknown and it's likely viral, specific prevention methods are unclear.

Often resolves on its own in 6-8 weeks. Anti-itch lotions, antihistamines, or light therapy can soothe symptoms.

Myth: It's a severe allergic reaction. Fact: It's a harmless, though annoying, rash that usually runs its course without long-term issues.

To confirm the diagnosis, as it can mimic other conditions like ringworm or secondary syphilis.
