40
how does CEOT appear on x-ray and where does it occur?
UNI or multiocular RL with RO mass and usually occurs with adults more in mandible in the premolar and molar area... surgical excision for treatment
41
who is adenoid cystic carcinoma more common in and how's it treated?
women... surgical excision. poor prognosis if matastisizes
42
this is the most common of all benign tumors and is a slow enlarging, nonulcerated, painless, dome shaped mass and is histologically an encapsulated tumor of missed tissues
pleomorphic adenoma
43
this histologically may show epithelial dysplasia or squamous cell carcinoma... if it is found in the floor of the mouth or lateral border of the tongue it needs to be biopsied
leukoplakia
44
what indicates tumor?
suffix "oma"
45
this is a form of SCC that has a better prognosis and slow growing exophytic tumor with a pebbly white/red surface and treat with surgical excision
Verrucous Carcinoma
46
means disordered growth
dysplasia
47
benign, slow growing aggressive epithelial odontogenic tumor occurring in both maxillary and mandibular area and means death when in maxilla... resembles RL honeycomb on x-ray
amelobastoma
48
tumor
neoplasm
49
benign tumor of salivary gland
adenoma
50
these are derived from tooth forming tissues
odontogenic tumors
51
an oral mucosal lesion that may appear as a smooth red patch or a granular red and velvety patch and less common than leukoplakia
erythroplakia
52
tumor of bone
osteoma
53
how is adenomatoid odontogenic tumor (AOT or OAT) treated?
enculation (removed all of it)
54
gland like
adenomatoid
55
this is a cementoma but not a neoplasm, teeth are vital... fibro osseous lesion and no freakin

invasion
57
a mass of cells exhibiting uncontrolled proliferation
neoplasm
58
what are the risk factors and treatments of SCC?
tobacco and alcohol surgical excision with or without radition or chemo (95% 5 year survival rate if detected early).. smaller the lesion the better the prognosis
59
this is a benign nonencapsulated odtontogenic tumor composed of both strands and small islands of odontogenic epithelium and tissue that resembles dental papilla

68
calcifications resemble bone trabeculae
ossifyinf fibroma

who does odontogenic myxoma occur in?
young people 10-29 years
72
this is a pre malignant condition that precedes squamous cell carcinoma, it looks like leukoplakia, erythoplakia or soeckled leukoplakia.. aka carcinoma in situ
epithelial dysplasia
73
what is the essential feature of SCC?
the invasion of tumor cells through the epithelial basement membrane into the underlying CT
74
who does pleomorphic adenoma occur in and how is it treated?
usually older people (40's) and surgical removal
75
benign well circumscribed tumor composed of fibrous CT and rounded or globular calcifications resembling cementum... considered fibro ossetia lesion because of fibrous CT and calcifications

mucoepidermoid carcinoma
86
this is a benign tumor of squamous epithelium that appears clinically as a relatively small esophagus pedunculated or sessile growth
papilloma
87
disordered growth
