Medical term for a group of skin conditions characterized by small, flat-topped, shiny bumps. Often used in compound names like 扁平苔癬 (lichen planus).
I was diagnosed with lichen at the dermatology clinic.
Lichen planus is often accompanied by itching.
lichen planus
keratosis pilaris; chicken skin
From Chinese 苔癬 (táixuǎn), literally 'moss ringworm', referring to the moss-like appearance of the skin lesions.
