Acute postinfectious pityriasis rubra pilaris (PRP) is a variant of juvenile PRP (Griffiths type III) characterized by no family history, an acute course associated with a prior fever, and good prognosis. Clinical features may resemble other superantigen-mediated diseases, such as scarlatiniform rash or staphylococcal scalded skin syndrome, but its histology and treatment are different. We present 4 cases of acute postinfectious PRP that illustrate the clinical features of this uncommon disease and we review possible underlying pathogenic mechanisms.
