A 48 year old Korean male was admitted to Chonnam University Hospital on April 6, 1966 with 40 years history of right otorrhea. 6 months prior to admission radical mastoidectomy was performed at a private E.N.T. clinic. According to post operative note, the bony external canal, tympanic cavity and mastoid antrum are filled with dark reddish granulation mass. The malleus and incus were disappeared. 8 weeks prior to admission, retroauricular discharge and otalgia was noted. 3 weeks prior to admission, adult fist sized hard ulcerated tumor mass was rapidly developed on the retroauricular region and auricle associated with hearing impairment and facial nerve paralysis. X-ray study of the temporal bone revealed extensive irregular destructive change in the mastoid tip, the occipital bone behind mastoid tip, the bony wall of external canal and the posterior portion of zygomatic arch on the right side. The above destructive process appears to extend into the petrous bone with marked destruction of the mastoid antrum and tegmen tympani. In addition, there is large soft tissue mass in size of 12×5.5cm the right external auditory canal. Specimen was taken from the mass and histopathological examination revealed squamous cell carcinoma of the right external ear and middle ear.
