Pustular Psoriasis (cont.)

When to Seek Medical Care for Pustular Psoriasis

An individual should visit a doctor if he or she has a rash of raised, pus-filled bumps on the skin, especially if he or she has generalized symptoms such as headache, fever, chills, joint pain, a feeling of general discomfort or uneasiness, decreased appetite, and nausea. It is important for a physician to evaluate the individual for a potentially curable condition caused by an infectious organism as well as consider whether or not one may have another associated chronic problem.

Visit a doctor anytime one has sores of any type in the mouth or throat that make it difficult to breathe or swallow.

Diagnosis of Pustular Psoriasis

A doctor may perform blood tests, including the following:

  • A complete blood count will often reveal reduced lymphocytes (lymphopenia), a type of white blood cell with a large number of another type of leukocyte called polymorphonuclear leukocytes, as high as 40,000 per microliter of blood.
  • The erythrocyte sedimentation rate is typically elevated, indicating inflammation.
  • Serum chemistry (breakdown of the levels of various components of your blood) can reveal increased plasma globulins (a type protein in the blood) and decreased albumin (a simple protein), calcium, and zinc.

A doctor may take a small sample of a pustule's contents to perform a culture. The results from these cultures and blood cultures are usually negative (no sign of infection). Since the skin is damaged, it may become infected, and the cultures are important.
