Early presentation of pityriasis rubra pilaris.
Pityriasis rubra pilaris (PRP), a disorder of epidermal proliferation and altered keratinization, typically first appears as a scaly, erythematous patch on the upper portion of the body. Its initial appearance is nonspecific and may be confused with other common dermatoses. Subtle clinical findings and histologic changes in the early stage of PRP are helpful in the early diagnosis of this condition. We describe two cases to illustrate the initial manifestations of PRP and review the literature, emphasizing its early presentation and treatment.
