Chapter 22 : Epithelial tumours of the external auditory meatus and middle ear

چکیده
Case reports of cancer of the ear began to appear about 1875. Furstenberg (19240 stated that carcinoma of the ear was first reported around 1775 by Wilde, Schwartze and others, but this statement is wrong: first because histopathology was not available in 1775; and second because Wilde was not born until 1815 and Schwartze not until 1837! This typographical error was later copied by others and illustrates well the dangers of quoting historical references secondhand, particularly when the original paper is in another language.
