Fig 3 Histopathologic features of benign alveolar ridge keratosis (BARK) (oral lichen simplex chronicus [LSC]). A, BARK is characterized by moderate to marked hyperorthokeratosis, mild surface papillomatosis, and acanthosis with wedge-shaped hypergranulosis (B) (arrows) and long, tapered, anastomosing rete pegs. C, Note hyperorthokeratosis and wedge-shaped hypergranulosis. D, LSC of skin. (Hematoxylin-eosin stain; original magnification: A, ×4; B and D, ×10; C, ×40.)
