  1. Histology Lichen planus can usually be diagnosed clinically and histology is not often required. Skin biopsy is characteristic: There is a 'saw-tooth' pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal band-like lymphohistiocytic infiltrate (mainly T cells)
  2. Lichen planus on the skin often clears up on its own in months to years. If the disease affects your mucous membranes, it tends to be more resistant to treatment and prone to recur. Whatever treatment you use, you'll need to visit your doctor for follow-up appointments about once a year
