Psoriasis often undiagnosed cause of skin symptoms in children: Children who suffer from the skin disorder called psoriasis can often go undiagnosed. The main problem is that psoriasis is rare in children, and not often seen by physicians for this reason. children may receive treatment for fungal skin infections. See misdiagnosis of psoriasis or symptoms of psoriasis.

Failure To Diagnose Psoriasis

Failure to diagnose Psoriasis may be associated with the following:

  • Many people who suffer from psoriasis may have an undiagnosed subtype of the condition called psoriatic arthritis
  • The failure to diagnose and treat a serious form of psoriasis called generalized pustular psoriasis can result in death

  • Psoriatic arthritis can be misdiagnosed when the presentation mainly involves joint symptoms and there are few skin symptoms present
  • Patients may be hesitant about speaking to their doctor about psoriasis symptoms that occur in genital areas and thus it remains undiagnosed

  • Irreversible joint damage can occur if psoriatic arthritis is not diagnosed and treated
