case_images: (a) H&E stain; original magnification is x4, while magnification in (b) is x10 and magnification in (c) is x40. Photomicrograph showing parakeratinised stratified squamous surface epithelium with branching and anastomosing rete ridges and connective tissue showing subepithelial deposits of homogenous eosinophilic material that resembled amyloid. The deeper parts show a diffuse mixed inflammatory cell infiltrate comprising predominantly of neutrophils.
