ORAL TUMORS

SQUAMOUS CELL CARCINOMA OF THE TONSIL

• Left tonsillar squamous cell carcinoma exhibits enlargement and ulceration of the tonsil. • Between the ages of 50 and 70.

• History of smoking and drinking alcohol. 

CANCER METASTASIS

LYMPHOMA OF THE TONSIL

• Second most common type of tonsillar malignancy. • Submucosal mass in an asymmetrical enlargement of one

tonsil. • Multiple enlarged lymph nodes commonly are observed on

the same side of the neck.

Ludwig's Angina

• Inflammation of the submandibular space ( submaxillary space sublingual space via the fascial planes NOT the lymphatics.

• submandibular space is expanded by cellulitis or abscess formation, floor of the mouth becomes indurated tongue is forced upward and backward, airway obstruction.

• Does NOT to mature and form an abscess, it is more likely to produce a cellulitis or a phlegmon.

CLINICAL MANFESTATIONS• Bilateral • Drooling, • Trismus, • Pain, • Dysphagia, • Submandibular swelling • Airway obstruction caused by displacement of the tongue. • Tongue protrusion outside the mouth.

MANAGEMENT• life-threatening condition that requires tracheotomy.

KAPOSI’S SARCOMA

• Small, painless, flat area (lesion) or lump, ranging in colour from brown or brown-red to reddish purple.

• Affect other parts of the body, most commonly the lymph nodes, the lungs and the organs of the digestive system (the gut).

• Signs and symptoms of internal KS depend on the site of the lesion.

• Common in AIDS-related KS,

• lymphoedema and is caused by the KS cells blocking the lymph nodes and disrupting the normal circulation of lymph fluid around the body.

Pleomorphic AdenomaBenign Mixed Tumor 

• Most common parotid gland tumor.

• 70-80% of all benign parotid tumors. 

• Over 84% of pleomorphic adenomas occur in the parotid gland, 8% occur in the submandibular gland, and 6.4% occur in the minor salivary glands.

• middle aged women

• Sarcomatous transformation is seen in only 2-5% of cases and is usually associated with tumors that have been present for 10-15 years. 

CLINICAL MANIFESTATION

• Painless slowly growing mass. 

• Solitary and well demarcated.

GROSS

• Heterogeneous secondary to hemorrhage, calcification, and necrosis.

Warthin's TumorBenign Papillary Cystadenoma Lymphomatosum

• Second most common benign tumor of the parotid gland.• It accounts for 2-10% of all parotid gland tumors. • More common in older white men and is the most likely

to be bilateral in 10% of the cases.
