[Tophaceous gout as a differential diagnosis of preauricular tumor].

Primary gout is a hereditary disorder in nucleotide metabolism. In addition to typical manifestations in the feet, hands, and large joints, there may be rare manifestations in the head and neck. We report a case of tophaceous gout in the temporomandibular joint in a patient who presented with preauricular swelling and progressive hearing impairment. Physical examination showed obliteration of the auditory canal and imaging revealed a destructive process involving the skull base. The diagnosis was confirmed by imaging and biopsy.      «
