Psoriasis & Lichen Planus

Psoriasis & Lichen Planus

Lichen Planus & Psoriasis are skin conditions that cause scaly patches or rashes on the skin. These two skin conditions have similar symptoms but have different causes and treatments.
Lichen Planus is an inflammatory disorder in which the skin appears as shiny, reddish bumps. Psoriasis is an autoimmune disorder in which thick red patches (known as plaques) of skin is covered in silver or white scales.

Symptoms of Lichen Planus:

  • Shiny, firm, reddish bumps
  • Bumps that are itchy
  • Often occur on wrists, lower back or ankles
  • May appear under fingernails
  • Symptoms disappear without treatment after a year

Symptoms of Lichen Planus:

  • Thick Red patches of dry skin
  • Plaques with white or silver scales
  • Plaques that are itchy
  • Develop on elbows, knees, scalp or lower back
  • Cause yellow fingernails or toenails
  • Symptoms are long term with no known cure

Causes of Lichen Planus & Psoriasis:

Psoriasis results from an immune system disorder which causes the body to attack its own healthy cells. In response, skin cells rapidly multiply leading to buildup of plaques.
Lichen Planus may develop as a response to use of certain medicines. It may also occur as a complication of Chronic Hepatitis C.

How are they Diagnosed?

Both of these skin conditions are diagnosed by examining a person’s skin, enquiring the patient about symptoms and family history.
In some cases, a biopsy may be necessary to rule out other related conditions

What are the Treatment Options?

Lichen Planus often clears up on its own and does not require any treatment. In case of painful outbreaks or severe itchiness, your doctor may prescribe topical steroids or light therapy
