Psoriasis is an autoimmune, common and chronic skin condition, affecting approximately 1‑3% of the world population, regardless the gender.

It usually occurs as erythematosus plaques covered by silver scales, which are detached from the skin. It occurs mainly on the knees and elbows, the nails and scalp, but it can also occur anywhere on the human body and in different types. Depending on the type of psoriasis, the affected area can be red and scaly, or it can display blisters.

Psoriasis is a multi-factorial disease the causes of which can include genetic, immunological, environmental and psychological factors. Psoriasis causes pruritus in 60‑70% of the cases, it is not contagious, it is not caused by an allergy and is attributed to genetic or hereditary predisposition. Approximately, 1/3 of people with psoriasis have a member in their family with psoriasis.

The are 5 basic types of psoriasis:

  • Plaque psoriasis
  • Guttate psoriasis
  • Inverse psoriasis
  • Pustural psoriasis
  • Erythrodermic psoriasis
  • Nail psoriasis
  • Psoriatic arthritis

Additionally, depending on its clinical stage, psoriasis is characterized as:

  • Acute guttate – rapidly progressing psoriasis
  • Chronic progressive psoriasis
  • Chronic stationary psoriasis
  • Chronis regressive psoriasis

and depending on its extent, the disease is classified as:

  • Mild (less than 3% of body surface)
  • Moderate (3-10% of body surface)
  • Severe (more than 10% of body surface)


In general, Psoriasis is a chronic disease with relapses and remissions. Yet, with proper treatment, patients can learn to leave with their condition and be in remission for a long time. The available current treatment options for psoriasis are:

  • Topical Steroids: Corticosteroids are frequently being used as initial treatment for small areas of mild to moderate forms of psoriasis, as they reduce the growth rate of skin cells and decrease inflammation and itching. Potent steroids should be used with caution, as their long-term use can lead to permanent skin sensitivity and atrophy.
  • Phototherapy: Involves exposing the skin to UV radiation from artificial sources, with or without concomitant medication, that increases the sensitivity of the skin to light. The light reduces inflammation, delays the production of skin cells and contributes to the elimination or reduction of psoriasis.
  • Excimer Laser Treatment: Its efficacy is the same with traditional Phototherapy, yet, fewer sessions are required as the laser light is stronger and penetrates deeper into the skin.
  • Use of Biological Agents: Widely used treatment method for severe forms of the disease and when conventional treatments have failed or there is an increases risk of toxicity form their use and if psoriasis is very unstable and dangerous or it significantly affects the quality of patient’s life. Before the administration of any biological agent, both clinical and laboratory investigations, as well as a vaccination program against flu, or any other vaccine that should be administered, should be conducted.

This autoimmune disease is considered an incurable; chronic skin condition and no definite cure has been found so far. It is not unlike for psoriasis to suddenly resolve and remain in remission, but often the symptoms return. However, most treatments contribute significantly to the suppression of symptoms with large periods of time of remission, improving patient’s quality of life.
