Could you recognise a lichen planus case if it were presented to you today?
Lichen planus is a non-infectious, itchy rash that can affect many areas of the body and skin lichen planus affects men and women equally. Genital lichen planus is often missed and can lead to scarring and functional problems.
Affected areas can include the:
- arms, legs and trunk
- mouth (oral lichen planus)
- nails and scalp
- vulva, vagina and penis (genital lichen planus)
“The exact cause isn't fully understood, but most experts believe it’s an autoimmune condition where the immune system mistakenly makes antibodies which attack healthy skin,” explains Dr Fiona Lewis, a consultant dermatologist at St John’s Institute of Dermatology, Guy’s and St Thomas’. “It’s not a subject that GPs receive a lot of training on, so it can sometimes be missed or mistaken for psoriasis, eczema or mouth ulcers”.
You can discover more about how to diagnose lichen planus, know when to refer your patient for a biopsy, and a range of other anogenital and oral dermatology conditions, on the 5th Annual Anogenital and Oral Dermatology course.
