Signs and symptoms of psoriasis may include the following:

  • Worsening of a long-term erythematous scaly area

  • Sudden onset of many small areas of scaly redness

  • Recent streptococcal throat infection, viral infection, immunization, use of antimalarial drug, or trauma

  • Pain (especially in erythrodermic psoriasis and in some cases of traumatized plaques or in the joints affected by psoriatic arthritis)

  • Pruritus (especially in eruptive, guttate psoriasis)

  • Afebrile (except in pustular or erythrodermic psoriasis, in which the patient may have high fever)

  • Dystrophic nails, which may resemble onychomycosis

  • Long-term, steroid-responsive rash with recent presentation of joint pain

  • Joint pain (psoriatic arthritis) without any visible skin findings

  • Conjunctivitis or blepharitis
