Isolated dermal lymphocytes from the infiltrate of mycosis fungoides show on scanning electron microscopic examination following characteristics, which differ from normal lymphocyte surface: loss of the round cell shape, increase of absolute length of microvilli, increase of lymphocytes with smooth surface and mitoses. These alterations concern all immunologic subpopulations and may indicate a stimulation of the whole dermal infiltrate in mycosis fungoides.
