[The microstructural surface of the non cornified squamous cell carcinoma of the human cord (author's transl)].

The microstructural surface of non cornified squamous cell carcinomas of human vocal cords are described scanning-electron-microscopically. Numerous bud-like cytoplasmic protuberances like microvilli, mostly close together are found, so that a considerable enlargement of the cell-surface results. For this reason a possible metabolism with resorptive function on the surface of non cornified squamous cell carcinomas might be drawn scanning-electron-microscopically. The surface of normal squamous cells of human vocal cords show microplicae mostly parallel arranged to each other. In the margin of non cornified squamous cell carcinomas there are as well bud-like cytoplasmic protuberances like microvilli as microplicae.
