All of the following regarding Lichen planus are true except -: (A) Does not involve mucous membrane, (B) Associated with Hepatitis 'C', (C) Topical steroids are the mainstay of therapy, (D) Spontaneous remission occurs after 6months to 2 years
Answer is A. Mucous membranes are commonly involved especially of oral mucosa, and less commonly of genital tract.

Topical steroids are the first line of treatment.
