Psoriasis is a common inflammatory skin disease that is associated with joint, psychiatric, and cardiovascular comorbidities. Diagnosis of plaque psoriasis is dependent primarily on characteristic physical findings and history. Given the varied clinical presentations of psoriasis and its mimicry to other papulosquamous skin diseases, it may be difficult for nondermatologists to diagnose psoriasis. Currently, no diagnostic criteria for plaque psoriasis have been validated in clinical studies. In this paper, we provide diagnostic guidelines for the nondermatologist to aid them in recognizing psoriasis.
