There are acute conditions that appear much as psoriasis, a rash that is red and often scaly. Pityriasis rosea is the most common form of this type of rash. It appears as an annular patch that looks like ringworm and is commonly referred to as a herald patch. Later other similar areas appear on the trunk and extremities. Pityriasis rosea often spares sun-exposed areas. This condition lasts 6-12 weeks and may spontaneously resolve.* The time frame and absence of future recurrence suggest that this condition is virally mediated. Non-soap cleansers, moisturizers and, sometimes, topical steroids are helpful.* Outdoor sunlight therapy, without burning is often the most helpful therapeutic agent.* It will often quickly induce a remission.*
