Lichen planopilaris (also known as "Acuminatus," "Follicular lichen planus," "Lichen planus follicularis," and "Peripilaris") is a form of hair loss which involves scarring, a follicular form of lichen planus, and is considered to have an autoimmune cause. Lichen planopilaris is a distinct variant of cicatricial alopecia, a group of rare disorders which destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss.
Famous quotes containing the word lichen:
“What do the botanists know? Our lives should go between the lichen and the bark. The eye may see for the hand, but not for the mind. We are still being born, and have as yet but a dim vision of sea and land, sun, moon, and stars, and shall not see clearly till after nine days at least.”
—Henry David Thoreau (1817–1862)
