Not common cause: Lichen planus can be caused by sulfonamides, tetracycline, NSAIDs, hydrochlorthiazide, and allergy to mercury & other metal containing amalgams as in dental fillings. It is of interest that Hepatitis C infection is found with greater frequency in lichen planus patients. Have your dermatologist keep a careful eye on your lesion.

Lichen Planus: The cause is unknown, but it is thought to be the result of an autoimmune process with an unknown initial trigger. Doubt the Fellatio has anything to do with it.
