This is the most common type. Problems may be:

  • Red, raised skin patches (plaques) topped by silvery-white scales that shed
  • Patches that often are on both sides of the elbows, knees, scalp, buttocks, or lower back
  • Patches that join to form large areas on the back and chest
  • On a few areas or on the entire body
  • Painful and cracking skin, often on the hands, fingers, and bottoms of the feet
  • Itchy skin

Some people may also have nail problems, such as:

  • Pitting
  • A yellow-red nail bed
  • Build up under the nail
  • Nails that pull away from the skin

This type results in small, red dots on the torso, arms, or legs.

This type results in pus-filled blisters and red skin. It can happen on the hands and feet with or without patches. There is also a form that can cover most of the body. The blisters appear, dry, and then peel over several days. A person may also have a fever.

This type results in:

  • Smooth, pink or red, mostly dry patches without scales
  • A rash that may be painful and get worse with friction and sweating

This is a rare, severe type that needs to be treated right away. It results in:

  • Red, swollen, scaly skin over most of the body
  • Scales that peel off in large pieces
  • Painful, itchy skin
