This is reflected clinically by profuse scaling histologically by a greatly thickened epidermis with increased mitotic activity and by the presence of immature nucleated cells in the horny layer and under the electron microscope by reduced production of intracellular filaments and granules seen within normal keratinization and biochemically by increased synthesis and degradation of nucleoproteins.
HISTOPATHOLOGICAL EXAMINATION: Histopathological examination in both cases shows hyperkeratosis and suprabasal acantholysis, abnormal keratinisation in the form of corps rond in stratum Malpighi and grains in horny layer are also seen.
