Alvin Friedman-Kien, MD, walked through the doorway into the exam room, looked at me and immediately said, “Oh, you have pityriasis rosea.” He called in a bunch of residents so he could show them my rash and teach them about the condition, which often has a large patch called the “mother patch” (or herald patch), as well as smaller
Pityriasis rosea (PR) is an inflammatory skin condition of uncertain etiology, although an unknown infectious agent has been suggested. PR manifests as an acute, self-limited, inflammatory eruption characterized in the majority of patients by a single larger lesion, the herald patch, followed by eruption of smaller papulosquamous oval lesions.
Pityriasis rosea je běžná vyrážka, která obvykle postihuje lidi ve věku 18–35 let a zasahuje tělo, ale ne obličej. Pityriasis rosea obvykle začíná jednou větší červenou skvrnou na hrudníku nebo zádech, na jejímž místě se nejdříve za dva dny objeví menší rozsáhlá vyrážka.
Pityriasis rosea is a self-limiting rash, resolving in about 6–10 weeks. The "herald patch" is a primary feature, usually found on the chest, abdomen, or back. DermNet provides Google Translate, a free machine translation service.
Synopsis. Pityriasis rosea is a common and typically self-limited cutaneous eruption.

The patients with a confirmed pityriasis rosea diagnosis were followed up for 4 years in order to investigate the recurrence rate. Of the clinically suspected patients, having a typical history of pityriasis rosea manifestations, a herald patch, and/or secondary coloured squamous lesions, 400 were confirmed by biopsy to have pityriasis rosea.
Symptoms. The main symptoms of pityriasis rosea are the appearance of the herald patch followed by a more diffuse rash of smaller patches. The patches tend to be oval, scaly, and dry to the touch. They may be pink, red or brown and generally appear on the abdomen, back, neck, arms and legs. Only rarely do the patches appear on the face.
