|
|
|
Whats a tori lesion
|
benign most common lump in oral cavity midline of palate or lingual of the mandible slow growing or static mandibular tori- usually symmetrical |
|
|
what a adenoma lesion |
benign smooth, round, swellings usually on hard palate arise from minor salivary glands |
|
|
whats a haemangioma lesion |
benign tumor-like proliferation of blood vessels (endothelial cells). usually occur early in life and may resolve
may be capillary (superficial) or cavernous (deeper and contain blood-filled spaces)- no pulse
soft bluish non-fluctuant nodule
tx if necessary by laser therapy, cryosurgery, sclerosing solutions- risk of haemorrhage |
|
|
whats a papilloma lesion |
benign pink-white pedunculated, exophytic lesion with cauliflower surface usually less than 1cm 21-50 age group
|
|
|
premalignant lesions |
leukoplakia erythroplakia
|
|
|
what is leukoplakia lesion |
premalignant white patch or plaque on oral mucosa membrane that cannot be characterised clinically or pathologically as any other disease- diagnosis of exclusion
usually show hyperkaratosis, can be dysplastic
appearance= homogeneous, speckled, verrucous or combination |
|
|
clinical feats of leukoplakia lesion |
occurs more in middle age/ older patients, smokers other association inc: trauma, alcohol, viral infections
locations- buccal mucosa, alveolar mucosa, lower lip more common floor of mouth, lateral border of tongue and lower lip are more 'sinister' sites |
|

|
|
erythroplakia lesions info |
premalignant bright red velvety patch that cannot be characterised clinically or pathologically as any other disease- diagnosis of exclusion
more likely to show dysplastic change |
|
|
clinical feats of erythroplakia |
clinical feats- occurs more in older patients
location- floor of mouth, lateral border of tongue, retromolar pad, soft palate more common
high risk of malignancy- 51% are invasive carcinoma, 41% carcinoma in situ |
|
