What skin condition is indicated by multiple salmon-pink patches after a sore throat?

The presentation of multiple salmon-pink patches following a sore throat is characteristic of pityriasis rosea. This condition often begins with a "herald patch," which is a single, larger patch that appears before the smaller, salmon-colored lesions develop across the body, often in a Christmas tree pattern on the back.

Pityriasis rosea is associated with the reactivation of certain viral infections, and it frequently follows upper respiratory infections like sore throats. The lesions typically present as macules or papules and are often pruritic (itchy).

In contrast, psoriasis typically presents with well-defined, scaly plaques and is not usually preceded by a viral infection. Eczema, or atopic dermatitis, usually manifests as itchy, inflamed skin and tends to have a more chronic course with possible flare-ups, rather than the acute presentation following a viral illness. Ringworm, a fungal infection, would present with ring-shaped patches with a clearer center and scaling but lacks the salmon-pink coloration and pattern seen in pityriasis rosea.
