Pityriasis rubra pilaris[edit]

Whitish keratotic plugs and linear vessels either solely or mixed with dotted vessels on a yellowish background are the most frequent dermoscopic features reported for pityriasis rubra pilaris.[1] This observation suggests that pityriasis rubra pilaris shows no typical characteristics of psoriasis, which is the most common differential diagnosis.
