A buccal exostosis is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. More commonly seen in the maxilla than the mandible, buccal exostoses are considered to be site specific. Existing as asymptomatic bony nodules, buccal exostoses don’t usually present until adult life, and some consider buccal exostoses to be a variation of normal anatomy rather than disease. Bone is thought to become hyperplastic, consisting of mature cortical and trabecular bone with a smooth outer surface. They are less common when compared with mandibular tori. Signs and symptoms
Buccal exostoses are bony hamartomas, which are non- malignant, exophytic nodular outgrowths of dense cortical bone that are relatively avascular.’Symptoms:
Buccal exostoses generally tend to be asymptomatic and are usually painless. However, they may increase patient concern about poor aesthetics, inability to perform oral hygiene procedures due to difficulty in cleaning around the area with a toothbrush, and compromised periodontal health by causing food lodgement, which could lead to patients reporting increased bleeding when tooth brushing. Signs:

They tend to appear in early adolescence and may very slowly increase in size with time. Buccal exostoses generally occur bilaterally. Found usually in the premolar and molar region. These benign growths affect both the jaws. The maxilla is shown to display a higher prevalence rate of 5.1:1 in comparison to mandible. Males also are afflicted more than females with a prevalence rate of 1.66:1, in all intraoral locations.The overlying mucosa appears to be stretched but intact and normal in colour.
Cervical lymphadenopathy refers to lymphadenopathy of the cervical lymph nodes (the glands in the neck). The term lymphadenopathy strictly speaking refers to disease of the lymph nodes, though it is often used to describe the enlargement of the lymph nodes. Similarly, the term lymphadenitis refers to inflammation of a lymph node, but often it is used as a synonym of lymphadenopathy. Cervical lymphadenopathy is a sign or a symptom, not a diagnosis. The causes are varied, and may be inflammatory, degenerative, or neoplastic. In adults, healthy lymph nodes can be palpable (able to be felt), in the axilla, neck and groin. In children up to the age of 12 cervical nodes up to 1 cm in size may be palpable and this may not signify any disease. If nodes heal by resolution or scarring after being inflamed, they may remain palpable thereafter. In children, most palpable cervical lymphadenopathy is reactive or infective. In individuals over the age of 50, metastatic enlargement from cancers (most commonly squamous cell carcinomas) of the aerodigestive tract should be considered. Classification
Cervical lymphadenopathy can be thought of as local where only the cervical lymph nodes are affected, or general where all the lymph nodes of the body are affected. Causes
Infection
Pericoronitis
Staphylococcal lymphadenitis
Mycobacterial lymphadenitis
Rubella
Cat scratch fever
Infectious mononucleosis
Streptococcal pharyngitis
Viral respiratory infection
Toxoplasmosis
Tuberculosis
Brucellosis
Primary herpes simplex infection (primary herpetic gingivostomatitis)
Syphilis (secondary)
Cytomegalovirus
Human immunodeficiency virus
Histoplasmosis
Chicken pox

Malignancy
Lymph nodes may become enlarged in malignant disease. This cervical lymphadenopathy may be reactive or metastatic.
