I think your experience has to do with streptodermia SICA which is clinically similar.

Pityriasis rosea is a rash of unknown cause which lasts about six weeks. Pityriasis rosea most often affects teenagers or young adults. In some cases there are no other symptoms, but it often follows a few days after a upper respiratory viral infection (cough, cold, sore throat or similar). A single scaling patch appears one to twenty days before the general rash. It is an oval pink or red plaque 2-5 cm in diameter, with a scale trailing just inside the edge of the lesion. The herald patch is often mistaken as ringworm. It can also be confused with psoriasis.

A few days later, more scaly patches (flat lesions) or plaques (thickened lesions) appear on the chest and back. A few may also appear on the thighs, upper arms and neck but they are uncommon on the face or scalp. These secondary lesions tend to be smaller than the herald patch.

PR lesions on face are uncommon except for a rare herald patch or PR inversus.

I've seen more PR now than before in my area, Vitória-Brazil, and the cause for that is still unknown. However PR lesions in face is still rare.

Also in my experience in Portugal, PR lesions on face are uncommon. However we are seeing clinical conditions that simulates PR but are sometimes viral infections much more papulous and eventually in atypical body areas.

As well as other colleagues comment, PR lesions on the face are extremely rare. I have seen a few cases with this location, always associated to other uncommon manifestations (fever, facial oedema,,,); facial lesions were unique herald plaque or more than one herald-like ones (larger than the "second generation" common elements). They justified a short low dose systemic corticosteroid treatment that shortened evolution and cleared fever and oedema when present..

PR lesions in face are extremely rare. Just 1 case in 15 years experience.

In tropical áreas of Brazil, as

I'd never seen facial lesion in PR in 30 years experience. Instead, herald patch is quite common on the neck, sometimes just in the sub-mandibular area.
