A Rare Case of Abducens Nerve Palsy Caused by Primary Squamous Cell Carcinoma of the Middle Ear.

Abducens nerve palsy is the most common ocular motor nerve palsy, and its possible aetiologies are numerous and diverse. Primary malignancy rarely occurs in the middle ear, with most cases associated with long-standing ear discharge and peak age of presentation in the sixties. We report a rare case of a 64-year-old male who presented with right abducens nerve palsy, which led to the diagnosis of primary squamous cell carcinoma of the right middle ear, and to our knowledge, this has not been reported previously in English literature.
