Living with lp - a patients guide
LI CHEN PLANUS affects around 1-2% of the population and is
thought to be an auto-immune disease which can affect the skin,
o ral or genital mucosa and more. The cause is unknown.
U K Lichen Planus (UKLP) was set up by Bridie Nelson in November
2007 to fill the gap in support for those living with the disease
Lichen Planus (LP). The group is open to members worldwide,
h owever treatments discussed are based on those used in the UK.

Li chen planus is an inflammatory skin disease which commonly
causes an itchy rash of small purplish bumps. Often the arms, legs,
b ack or inside of the mouth are affected, however it can also affect
the genital area including the vagina or penis. Lichen planus may
o ccasionally involve the nail, hair and scalp or the skin around the
anus (back passage). Very rarely, it may involve the oesophagus or
tear ducts. It is possible to have the disease in one area without
WHAT CAUSES IT
The cause of lichen planus is unknown. We know that it is NOT
c aused by infection, hormonal changes or ageing, and is not
because of anything that you did or didn't do. It results from
nflammation in the skin. There may be a problem with our
mmune system, the system that protects a person from infection.
In lichen planus the system may be overactive, making proteins
hat cause inflammation in the skin, mouth or in the genital area.
This is referred to as an autoimmune reaction. Occasionally
medicines can start this reaction. Why the lesions develop in some
places and not others is not known. Lichen planus is NOT
contagious and cannot be passed to a sexual partner.
There is no absolute cure for lichen planus. However, in some
c ases, lichen planus seems to come and go of its own accord and it
is possible that it will disappear completely. There are many
t reatments used to treat lichen planus and treatment needs to be s
elected to fit your problem. Different people respond to different
things. The medications will control but often will not cure the
li chen planus. In some cases, usually oral and genital LP, treatment
is a long process and close follow up with you and your caregiver is
U sually the disease can be treated with creams and ointments,
although some disease if causing no symptoms, will not need any
reatment. Generally topical steroid ointments are used safely in
this condition. These may be strong (potent) steroids (Dermovate)
o r milder ones combined with tetracycline (Trimovate) which may h ave an additional helpful effect. Erosive disease can be more
difficult to control but most respond to strong topical steroid
o intments or steroid and antibiotic creams. Some of the new
creams and ointments to suppress the immune reaction such as
acrolimus (Protopic) or pimecrolimus (Elidel) may also be used.
Occasionally oral or ׳other' medication to suppress the immune

has shiny flat-topped bumps of different sizes, purple in
colour and often crossed with white lines called Wickham's striae.
T hey are usually found on the inner wrists, forearms and ankles,
but can affect any part of the skin. LP may be very itchy. New
esions appear while others are clearing. Occasionally the skin
discolours after the lesion has cleared and this can remain for
s ome time. This form of LP often clears on its own.

almost half of the cases of LP, the mouth is involved, and
is often the only area to be affected. LP in the mouth may appear
a s white or red patches, white streaks, ulcers or painful red gums.
It may not cause any symptoms or only be sore occasionally. Some
s picy or acidic foods or hard foods may make the soreness worse. A fter appearing it is often present for life.
O RAL LP, how you can help yourself:
1. Avoid eating strong spicy foods, chilli, curry, citrus fruit, tomatoes or
strawberries - anything acidic e.g. fruit juices.
2. Avoid sharp foods e.g. crusty bread or crisps.
3. Avoid drinking alcohol, spirits in particular.
4. Try sticking to fairly bland food when lesions are painful, porridge,
softly boiled eggs, mashed potatoes etc.
5. Keep to your usual toothpaste if you can, otherwise in the short term,
try an alternative like Aloe-dent which is very mild and non irritating.
6. Use a mouthwash which doesn't contain alcohol eg Dentyl, or an
alcohol free chlorhexidine mouthwash and keep your mouth as clean

VULVAL / VAGINAL LP
soreness, burning and rawness are very
c ommon symptoms. If the outer layers of the skin break down
(erosions), these areas appear moist and red.There may be a white
acy pattern on the vulva.This pattern can also be seen around the
edges of the erosions. The vulva may appear pale white or
p ink/red. Scarring with loss of the inner lips (labia minora) can be s
een. The clitoris may be buried under scar tissue.
If the vagina is involved, intercourse can be painful. Erosions can
occur inside the vagina in a patchy or generalized pattern. Some
women have a sticky, yellow or yellow-green discharge, which
c an be bloodstained, especially after intercourse. If the two
surfaces of the vagina heal together, the vaginal opening can
b ecome narrowed. This is one reason why intercourse can be
painful. Sometimes it is difficult for a doctor to perform an internal
e xamination. Rarely, the skin may have thickened areas. These
shiny flat-topped bumps are common on the penis and
u sually occur around the tip (glans). Sometimes the bumps can
form rings. The erosive form of lichen planus is less common in
men but may occur. This may increase the risk of penile cancer.

after spending a penny, aqueous cream can also be used to wash with

4. Some members find that ice packs are useful to reduce itching and
swelling - if ice packs are not available, a pack of frozen peas will do
the same job but do not apply directly onto the skin as this may

What is the outlook (prognosis) for people with lichen planus?
n general, the outlook is good. Without treatment, about half of
cases of lichen planus affecting the skin clear within 6-9 months. It
is unusual for the rash to last longer than 18 months. Oral disease
ends to persist. Erosive disease of the vulva or penis tends to be
more persistent. However, lichen planus can persist longer in

What should I watch for?
Erosive lichen planus can carry a very small risk of developing local
ypes of skin cancer, the risk is about 2%. Regular self examination
is very important and if you become aware of any changes, or
persistent, non-healing areas in your mouth or genital area, these
hould be reported to your doctor. If detected early treatment is
very successful. It is important that your lichen planus is treated
