Lichen Planus

Lichen planus produces flat-topped, itchy, purple-toned bumps on the skin and can also involve the mouth, nails, and scalp — which is why it is frequently mistaken for other rashes. It is not contagious, and while its exact cause is not fully understood, it reflects an abnormal immune response that dermatologists can treat effectively. Dr. Blair Harris confirms the diagnosis, sometimes with a small biopsy, and tailors treatment to where the disease appears and how much it bothers you.

The exact cause of lichen planus is not well understood, but it is believed to involve an abnormal immune response that leads to inflammation. Genetic predisposition, certain medications, infections, and stress may play a role in triggering or exacerbating the condition.

• Cutaneous Lichen Planus

  Involves the skin.

• Oral Lichen Planus

  Affects the mucous membranes inside the mouth.

• Genital Lichen Planus

  Affects the genital area.

• Nail Lichen Planus

  Affects the nails.

• Lichen Planopilaris

  Involves the scalp and hair follicles, leading to hair loss.

Treatment options for lichen planus depend on the severity and areas affected. The primary goal is to manage symptoms, reduce inflammation, and prevent complications. Common treatment approaches include:

• Regular Follow-ups

  Close monitoring with a healthcare provider to determine the most appropriate treatment plan and track progress.

• Stress Management

  Finding ways to manage stress can help reduce flare-ups.

Most cases respond to prescription anti-inflammatory treatment, though oral and scalp involvement often calls for a more persistent approach. Because lichen planus can smolder and recur, we monitor your response at follow-up visits and adjust therapy until symptoms are controlled.
