- Where Does "Lichen Planus" Come From?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: When an itchy rash suddenly appeared on my body, I thought it was
- poison ivy, and that daily washing and a little patience would see me through.
- However, when it didn't fade I consulted my doctor, who told me I have a skin
- disease called "lichen planus". He is now treating me with lots of
- medication, but I still don't know where this came from or whether it will
- ever leave. Please help by discussing this disease.

- ANSWER: I am afraid there is not much known about the causes of this
- condition, although it does seem to appear more frequently in spring and
- summer. The itchy, irregular skin lesions may well be confused with poison
- ivy, for it may often appear most on the arms and legs; but since it may also
- appear on portions of the body that are covered and protected from contact
- with the leaves of the plant, and since the rash does not follow the course of
- the ivy induced rash, it is relatively easy to tell them apart. The lesions
- may also appear on the inner lining of the cheeks, in the mouth and on the
- lips, gum and tongue. This happens in just about half the cases. You may
- notice that if you injure your skin covering any part of your body, a rash
- similar to the ones you now have will appear. This is called an "isomorphic
- reaction" and is typical of lichen planus. There are some drugs that are
- associated with the appearance of these skin eruptions, and include arsenic,
- antimalarial agents, beta-adrenergic blockers, thiacide diuretics and gold
- salts. Be sure to mention any medications you may be taking to your
- physician. Treatment may include the use of some strong corticosteroid creams
- or ointments or oral griseofulvin. Whatever therapy your physician has
- chosen, it may be a while before all the lesions are gone. About 50% of
- patients on therapy clear in about 9 months, and by 18 months, 85% of the
- patients are rid of the rash. Patients who experienced sudden onset of the
- lesions as you did generally have more symptoms, but also tend to recover more
- rapidly as well. I hope you will be amongst the lucky ones.
