This is an even higher-power photomicrograph of the tracheal mucosa and the diphtheritic membrane. The mucosal surface of the trachea is ulcerated (total loss of epithelial cells) and the only remaining epithelial cells are found in the glands (arrows)...
This is an even higher-power photomicrograph of the tracheal mucosa and the diphtheritic membrane. The mucosal surface of the trachea is ulcerated (total loss of epithelial cells) and the only remaining epithelial cells are found in the glands (arrows). The diphtheritic membrane consists of fibrin and inflammatory cells, most of which are dead.
