The fine structure of a case of differentiated rhabdomyosarcoma of the ear is described. Characteristic actomyosin filaments have been demonstrated in thin sections showing cross-striation (Z bands). There were large numbers of ribonucleoprotein particles but no virus-like particles present. It is hoped that, as in other difficult or rare tumours, electron microscopy may provide an additional clue of some assistance to the pathologist in determining diagnosis or aetiology.

A chordoma was examined by electron microscopy. It was composed of stellate and physaliphorous cells. The fine structure of these cells is described. Transitional type cells are also described and it is suggested that the physaliphorous cells develop from the stellate cells through a process of vacuolation. Two types of vacuoles are described, ;smooth-walled' and ;villous' endowed with numerous structureless microvilli. Some observations on stained sections are discussed.
