What Is Psoriasiform Dermatitis?

Chapter

Abstract

Psoriasiform dermatitis is a histological term that refers to a group of disorders which histologically mimic psoriasis. Chief among them in frequency are lichenified dermatitis, seborrheic dermatitis, and pityriasis rubra pilaris. Other disorders include secondary syphilis, mycosis fungoides, and inflammatory linear verrucous epidermal nevus.

It is fair to expect that a histological diagnosis of psoriasiform dermatitis be accompanied by a differential diagnosis and the degree of likelihood of each of the suspected disorders. If a clinical differential diagnosis has been submitted on the requisition form, the pathologist is more likely to address the likelihood of each of the disorders.
