Most patients present with a very rapidly growing mass that often gives a bluish appearance in the mouth. This is because the pigmentation in the cells appears blue through the overlying epithelium (mucosa). By imaging studies, there is usually a large expansive radiolucent (clear) mass without well defined borders. Calcifications within the mass may be seen. More than 70% involve the maxilla (usually maxillary anterior alveolar ridge), while the mandible and skull are affected less often. There is often an elevated vanilmandelic acid level.
