title: Membrane activity in histiocytic diseases of the skin.
abstract: Study of the histiocytes from a large variety of skin diseases demonstrates a close relationship between the cell processes peculiar to those cells and their degree of phagocytic activity. The membrane structures, as well as the dense bodies localized in the peripheral cytoplasm, suggest a type of endocytosis distinct from pinocytosis and phagocytosis.
