Junctional nevus is the rarest type of oral nevus and only three well-documented cases have been reported. The present study adds a fourth case to the literature. Junctional nevus must be carefully differentiated from atypical melanocytic hyperplasia and malignant melanoma, which are clinically similar lesions. Because their malignant potential is uncertain, it is recommended that oral junctional nevi be completely excised. The classification of pigmented nevi of skin and mucous membrane and the concepts of their relationship to malignant melanomas have been changing. The authors recommend a classification for oral lesions based on the work of Sagebiel.

Eagle's syndrome is the symptomatic elongation of the styloid process of the temporal bone. It is an uncommon clinical entity that often causes vague and seemingly inconsistent symptoms. The pain associated with this syndrome is relieved by amputation of the elongated portion of the styloid process. The regional anatomy and possible causes of the pain were discussed. An improvement in the surgical approach, which aids in visualization and assures the retraction and deflection of significant adjacent anatomical structures, has been suggested. Three cases were presented that had varying symptoms but apparently common etiologies. This syndrome should be considered when considering the differential diagnosis of facial pain.
