• As Medline Plus explains, psoriasis is a skin condition characterized by redness and irritation. It can affect any area of the body, including the ears, although psoriasis in the ears is fairly uncommon. The signs and symptoms of psoriasis in the ears are the same as psoriasis on other parts of the body, with the addition of possible hearing loss. Not everyone experiences all of these symptoms, but one or more symptoms are generally present in all cases.
  
  

Redness

• According to Medline Plus, psoriasis symptoms nearly always include patches of red, inflamed skin. In some cases, the redness may only be present as small dots. As the National Psoriasis Foundation points out, psoriasis in the ears usually only affects the outer part of the ear canal, so it should not be difficult for you or a friend to observe any inflamed skin present in your ears.
  
  

Raised or Thick Skin

• As Medline Plus points out, areas of red skin may also be raised up and thicker than normal, a symptom that may help you differentiate between psoriasis in your ears and ordinary inflammation from some other irritant.
  
  

Scales

• According to Medline Plus, plague psoriasis, the most common kind of psoriasis, includes the occurrence of silvery, flaky areas of skin called scales. Scales are usually surrounded by red skin. You may notice these scales building up in your ear canal.
  
  

Dry or Itchy Skin

• As the Mayo Clinic notes, dry or itchy skin is often a symptom of psoriasis. Dry skin may bleed, so you may notice some blood in your ear canal.
  
  

Painful Skin

• According to the Mayo Clinic, psoriasis symptoms may include painful or burning skin.
  
  

Blisters

• As Medline Plus notes, psoriasis can manifest itself in the appearance of white blisters among patches of red skin, a type of psoriasis called pustular psoriasis.
  
  

Hearing Loss

• According to the National Psoriasis Foundation, a unique symptom of psoriasis in the ears is hearing loss, as buildup of scales can block the ear canal. Hearing loss is usually temporary and resolves when a doctor removes the scale buildup.
  
  

Cyclical

• As the Mayo Clinic notes, psoriasis tends to be cyclical: you may experience severe symptoms for a few months, then find that your symptoms disappear for a time. For most people, psoriasis is chronic, even though it may not be present all the time.
