Lesions of the oral maxillofacial region that present as a mass


One of the most common diagnostic clinical problems is the patient who presents for evaluation with a mass in the oral cavity.  Developing a reasonable differential diagnosis of the lesion is the first step in managing such a patient.  The differential diagnosis serves a guide subsequent intervention and, if necessary, provides an appropriate basis for referral of the patient. The majority of these tumors fall into one of two categories.  They are either soft tissue or salivary tumors, including reactive conditions from these groups.  The frequency of such lesions varies from one specific site to another, so the tumor’s specific location is also a consideration in the differential diagnosis.
