Complications

Lichen planus can be difficult to manage on the vulva and in the vagina, causing severe pain and sometimes leaving scars. Sexual dysfunction can become a long-term complication. Oral sores may affect your ability to eat. The affected skin might stay slightly darker even after the rash clears up, especially in dark-skinned people.

Oral lichen planus increases the risk of oral cancer. Left untreated, lichen planus of the ear canal may lead to hearing loss.
