make sure. Your dermatologist may call this a
biopsy.
 Sometimes, you may need blood tests to rule out
other diseases.

5. Causes
One theory is that lichen planus is an autoimmune
disease.
 This means the person’s immune system reacts as
though the skin and other parts of the body are
foreign.
 When this happens, the body starts to attack itself.

6.  There may be a link between lichen planus and
infection with the hepatitis C virus. Many people
with hepatitis C also have lichen planus
 What causes most cases of lichen planus
remains unclear. Its is not known to spread by
any means from host to host

7. Treatments
 There is no cure for lichen planus. It often goes
away on its own. If symptoms are
bothersome, treatment often brings relief and
may speed healing.
 Pills. Pills can be prescribed to relieve itching
 Topical corticosteroid . Cream or ointment to
reduce swelling and redness
 PUVA therapy: A type of light treatment that can
help clear the skin. Typically used on more extreme
cases
