Abstract
Temporal bone carcinoma with intracranial extension
Highlights
Chronic otitis media and cholesteatoma are common in patients with temporal bone cancers and have been implicated as etiologic factors[5]
Human papilloma virus has been implicated in squamous cell carcinomas of the middle ear
Nodal metastasis is uncommon in early disease but may occur in 10-20% of cases of advanced disease[5]
Summary
Squamous Cell Carcinoma of the temporal bone is an uncommon entity accounting for fewer than 0.2% of all tumors of the head and neck and is associated with a poor outcome[1]. A 57 year old patient presented at the ENT OPD of Hamidia Hospital, Bhopal with complaints of discharge from right ear since 6 months, right preauricular swelling since 15 days and right sided facial nerve palsy since 15 days.On otologic examination there was a diffuse bony hard swelling of about 5x5cm involving the right preauricular and zygomatic region. External auditory canal was completely obliterated by a fleshy polypoidal mass covered with discharge. High resolution CT scan of temporal bone and head revealed a large soft tissue mass showed post contrast enhancement involving middle ear cavity and external auditory canal (fig 1).
