We have raised a polyclonal antibody to the 170-kD epidermal growth factor receptor. We found an intercellular pattern of immunoreactivity in the epidermis as well as a positivity of the cytoplasm of keratinocytes and eccrine secretory cells. In some samples, a nuclear labelling was evidenced in these type of cells. There is a close resemblance in the topographical distribution of these cells with nuclear labelling and those synthesizing DNA under phytohaemagglutinin stimulation.
