Pityriasis rosea is a self-limiting inflammatory disease with widespread, scaly papules and plaques. Treatment is usually not necessary.

Pityriasis rosea usually occurs between the ages of 10-35 years. It affects women more often. The cause could be a viral infection (some research has human herpes viruses 6, 7 and 8 associated). Drugs can lead to a PR-like reaction.

Pityriasis rosea is a self-limiting inflammatory disease with widespread, scaly papules and plaques. Treatment is usually not necessary. Pityriasis rosea usually occurs between the ages of 10-35 years. It affects women more often. The cause could be a viral infection (some research has human herpes viruses 6, 7 and 8 associated). Drugs can lead to a PR-like reaction. Symptoms and signs The disease typically begins with a single, 2-10 cm wide “primary medallion” on the trunk or proximal extremities. Within 7-14 days the generalized centripetal eruption of 0.5-2 cm rose-colored or fawn-colored oval papules and plaques follows. The lesions have a scaly, slightly raised edge (Collerette-scaling) and recall Ringel braid (tinea corporis). Most patients report a partially severe itching. Papules may predominate with little or no scaling in children and pregnant women. The pink or Rehbraunfärbung is not so obvious in patients with dark skin. Children have often an inverse PR (lesions in the armpits or groin that spread centrifugally). The classic lesions follow the lines of cleavage, so that a Christmas tree-like pattern arises when many lesions on the back are available. In a few patients before eruption of lesions a prodromal phase of malaise, headache and arthralgia sometimes occurs.
