  • Suprabasal acantholysis

    • When a vesicle is created by acantholysis, the intercellular bridges are lost (versus the phenomenon of spongiosis), and the detached solitary cells take on a rounded shape.
    • Unlike Grover’s disease, the acantholysis in Darier disease is more extensive
  • Hyperkeratosis

  • Papillomatosis and acanthosis
