47
leukoplakia
Intraoral white plaque that does not rub off and cannot be identified as any well-known entity. White because something is blocking the redness of the underlying vasculature. Precancer (dysplastic epithelium or SCCA 20%). 80% benign hyperkeratosis. 5-50% malignancy risk. Tobacco, alcohol (w tobacco), sanguinaria (maxillary vestibule or alveolar mucosa), UV radiation (lower lip vermillion), microorganisms (treponema pallidum), trauma (not precancer). Most common on lip, buccal, gingiva. Most common for cancer is lip, tongue, FOM. BIOPSY. Mild dysplasia (lower 1/3) moderate (lower ½). Severe (above the ½) In Situ (baby cancer). Follow up important because recurrence is common. Increase risk for cancer if female, persistant, nonsmoker, oral floor or ventral tongue.
48
risk of cancer
Low Leukoplakia, erythroleukoplakia, erythroplakia, proliferative verrucous leukoplakia (multiple keratotic plaques w roughened surfaces. Slowly spread) High
49
erythroplakia
red patch that cannot be identified as a well known entity. Never benign. Well-demarcated with a soft and velvety texture. Asymptomatic. Red due to underlying vasculature. Biopsy and long term follow up.
50

51
oral submuccous fibrosis
chronic, high risk, progressive, precancerous condition resulting from betel quid or paan. Palor (white) and fibrosis. Trismus and pain from spicy foods. Buccal, retromolar pad, soft palate. Will not fade with cessation. Follow up due to 10% chance of malignant transformation.
52
nicotine stomatitis/ reverse smoking
White/grey keratotic change on the palate. Due to heat (can get same in coffee drinkers) numerous slightly elevated red centered papules (ducts from minor salivary gland) completely reversible. REverse: red bleeding ulcerated, not reversible
53
actinic cheilosis
: premalignant change of the lower lip. Long term UV exposure. Older than 45. Atrophy of lower lip vermillion border, smooth surface and blotchy pale areas. Blurr the margin between vermillion and cutaneous portion. Scaly as it progresses. Transforms to SCCA (10%). Irreversible. Use lip balms with sunscreen to prevent further change.
54
squamous cell carcinoma
posterior/lateral tongue, FOM, soft palate, gingiva. Painless, indurated, typically FOm are from leukoplakia and are near midline, gingival and alveolar (least associated with tobacco. Look over in notes.
55
TNM staging
look in notes
56
verrucous carcinoma
low grade variant of oral SCC. Men older than 55. Mandibular vestibule and gingiva. Present 2 years before diagnosis. Diffuse, well-demarcated, painless, thick plaque with papillary or verruciform surface projections. White cauliflower looking thing. Surgical excision without neck dissection. Malignant transformation potential (most) PVL, nicotine stomatitis, erythroplakia, oral submucous fibrosis, erythroleukoplakia, granular leukoplakia, actinic cheilosis (least).
57
basal cell carcinoma
most common of all cancers. Locally invasive and slow spreading. Frequent sunburn and freckling as a child is a risk factor. Nodular is most common. Central depression with an umbilicated appearance. Telengiectatic blood vessels and rolled borders. Metastisis is rare. Other types are pigmented (same as nodular but clinically brown or black), sclerosing (morpheaform- mimics scar tissue and is deeply invasive). Superficial (skin of trunk, multiple red scaly patches resembles psoriasis) surgical excision (use frozen section to evaluate margins) death can occur if it invades vital structures
58
melanoma
melanocytic neoplasm. Arises from a benign lesion or from normal melanocytes. ACUTE sun exposure is a risk factor. Increases with a family hx, fair skin, light hair ect. 3 most common skin cancer. 1/3 with oral manifestation have a hx of a pigmented macule. In oral cavity or sinus it is bad news. Radical growth (lateral) and vertical growth. ABCDE. Depth of invasion correlates with prognosis. Surgical excision 3-5 cm margin. Radio resistant. New chemo is decent. BANS. Oral melanoma has 15-20% survival rate (distant metastasis).
59
mucocele
spillage of mucin into soft tissue due to rupture of a salivary gland. Lower lip, FOM (ranula), anterior ventral tongue, buccal mucosa. Upper lip is most likely salivary neoplasm retromolar area is usually mucoepidermoid carcinoma.
60
sialolith
salivary stone- calcifications. Most likely in submandibular gland (long twisty gland). Pain or swelling at meal time. Dx: radiograph, siolography, untrasound, CT. tx: massage, increase fluid intake, moist heat, sialogogue, surgery. Anything that inhibits salivary flow or production is a factor.
61
necrotizing sialometaplasia
locally destructive inflammatory condition of the salivary glands. Possibly from ischemia. Predisposing factors: trauma, dental injections, ill fitting dentures, uri, tumor, surgery. Non ulcerated swelling, pain, paresthesia-necrotic tissue sluffs- heal in 5-6 weeks. Biopsy to r/o possible malignancy.
62
cheilitis glandularis
swelling and eversion of the lower lip as a result of hypertrophy and inflammation of the minor salivary glands. Possible causes: sun damage, tobacco, syphilis, poor hygiene, genetic. Swelling and pain, eversion of lip, red dots (ductal orifices), weeping mucopurulent secretions, middle aged to older males.
63
xerostomia
dry mouth. Complications: candidiasis, cervical and root carries, taste alteration. Causes: medication, alcohol, caffeine, smoking, head and neck radiation, sjorgrens, diabetes mellitis, sarcoidosis, salivary gland surgery. Tx: remove causative agent, sugarless candy/gum, mouthwash.
64
sjorgrens
autoimmune attacking salivary gland (and other lacrimal glands). 85% female. Dry mouth and dry eyes (sicca). Primary ss: no other autoimmune disease. Secondary SS: associated with other autoimmune disorder. DX: (2/3) positive serum anti-SSA or SSB. Ocular staining score \>=3. Presence of inflammation in labial salivary gland biopsy. Exclude: radiation, hep C, AIDS, preexisting lymphoma, sarcoidosis, GVHD, anticholinergic drugs. Same tx as xerostomia, monitor for lymphoma.

salivary gland neoplasm summary
1-6.5/100,000. Parotid\> minor \> submandibular \> sublingual Chance of being benign. Major All (66%) Parotid (70%) Submd (60%) Subling(30%) Minor: Minor gland (50%) Upper lip (80) lower lip (40) palate (50) tongue (15) cheek (50) retromolar pad (10) More common in upper lip than lower lip. Upper lip mostly benign/lower lip usually malignant (90%). Most common is pleomorphic adenoma (benign). Most common malignant is mucoepidermoid carcinoma. palate is most common place for minor salivary gland neoplasm.
66
pleomorphic adenoma
benign mixed tumor. Most common neoplasm. Ductal and myoepthelial cells. Big amount of parotid gland and submd. Palate is most common for minor, upper lip, buccal mucosa. Encapsulated but grows until it’s treated.
67
warthins tumor
parotid cystadenoma lymphomatosum. Almost exclusively in parotid. Second most common benign parotid tumor. May occur bilaterally. Smokers have 8x the risk.
68
mucoepidermoid carcinoma
most common malignant in adults and children. Parotid then minor glands (palate). Prognosis on grade and stage submnd has poorer prognosis than the parotid gland.
69
adenoid cystic carcinoma
minor gland(50%), palate \> parotid, submnd. Most common malignant neoplasm of the submnd gland. Slow growing, widely infiltrative, tendency for perineural spread. Pain facial nerve paralysis. 20% survival rate in 20 years
70
polymorphous low grade adenocarcinoma
