Pityriasis Lichenoid Chronica (PLC)

General Information:

  • Pityriasis lichenoides is the name given to a rash with two variations
  • The condition has an acute and a chronic form
    • The mild chronic form, known as pityriasis lichenoides chronica (PLC), typically presents with symptomless, small, scaling small bumps that spontaneously flatten, turn brown and regress over a period of weeks
    • The acute form of pityriasis lichenoides, known as pityriasis lichenoides et varioliformis acuta (PLEVA), is characterized by the abrupt eruption of small scaling small bumps that develop into blisters and crusted red-brown spots
  • Pityriasis lichenoides most often affects adolescents and young adults, usually appearing before the age of 30
  • It is slightly more common in males
  • PLC most commonly occurs over the trunk, buttocks, arms and legs, but may also occur on the hands, feet, face and scalp
    • There are usually no symptoms
    • Often PLC may come and go, and can last for months or years
  • PLEVA is characterized by small scaly bumps which often becomes filled with pus and blood, or are crusted
    • PLEVA most often occurs on the trunk and extremities and the spots may be itchy or painful
  • The cause of pityriasis lichenoides is not yet known
  • Pityriasis Lichenoides is not contagious or due to diet

Treatment of PLEVA:

 

  • Pityriasis lichenoides may not always respond to treatment and frequently returns when treatment is stopped
  • The treatment for both PLC and PLEVA is the same
  • If the rash is not causing symptoms, treatment may not be necessary
  • Minor outbreaks can be controlled with various creams
  • If the rash is not responding after one month, you should contact your doctor
  • In severe cases stronger treatments such as Ultraviolet light or oral medications are required
    • These medications have numerous possible side effects and require careful monitoring by your doctor
