Abstract

A case of squamous cell carcinoma arising from external auditory canal in 48 years old woman was reported. It had originated in deep external auditory canal wall, and then extended to timpanic cavity, mastoid cells, parotid gland, bulbus jugularis, and fossa pterygopalatina.On hundred and twenty-six reported cases of cancer of the ear were collected from Japanese literetures. There were 42 cases of primary cancer of external auditory canal. Cancer developed from deep external auditory canal appears to be similar to middle ear cancer specially those so-called superficial form of Dr. Kirikae and Sawaki, but it is different from that developed from superficial external auditory canal.
