title: A ganglion associated with the temporomandibular joint.
abstract: A ganglion that occurred as a preauricular mass was reported. A review of the literature disclosed no previous report of a ganglion in this area. Although a ganglion is an innocuous lesion, its presence in the preauricular region must be considered a remote possibility in the differential diagnoses of masses in this area.
