Rare case of temporal bone carcinoma with intracranial extension.

Temporal bone cancer, a relatively rare disease, accounting for less than 0.2% of all tumors of the head and neck and is associated with a poor outcome; often presents in a subtle manner, which may delay diagnosis. It should be suspected in any case of persistent otitis media or otitis externa that fails to improve with adequate treatment. Despite advances in operative technique and postoperative care, long-term survival remains poor). It includes cancers arising from pinna that spreads to the temporal bone, primary tumors of the external auditory canal (EAC), middle ear, mastoid, petrous apex, and metastatic lesions to the temporal bone. Here is a report on a case of temporal bone carcinoma presenting with right otalgia, otorrhea and facial paralysis. The patient was initially diagnosed as mastoiditis and later the clinical impression was revised to temporal bone carcinoma (undifferentiated type), based on the pathologic findings.
