Figure 1: H&E stained sections with magnification of 4× (A) on light microscope showing hyperkeratosis, parakeratosis with prominent granular cell layer, and irregular acanthosis with elongation of rete ridges. Superficial dermis showed perivascular inflammatory infiltrate composed of lymphocytes and few polymorphs. The subcutis showed congested blood vessels and sparse mononuclear inflammatory cells.
