Lichen planus. Light micrograph of a section through skin affected by lichen planus,a clinically and histologically distinct form of dermatitis. The epidermis (upper layer) shows hyperkeratosis (flaky,red),above a thickening of the granular layer (dark pink). Below this there is acanthosis in the prickle cell layer (also dark pink). The basal layer shows characteristic hydropic degeneration,producing rete pegs (finger-like) and an irregular junction between the epidermis and the dermis (lower layer,light pink). The dermis shows a layer of dense chronic inflammatory cells | |
