24
Q

Mild epithelial dysplasia

Study These Flashcards
A

Cellular alterations limited to basal layer

25
Moderate epithelial dysplasia
Involvement from basal layer to mid portion of spinous layer
26
Severe epi dysplasia
Deeper alterations from basal layer to level above midpoint and may involve duct of a minor salivary gland
27
Carcinoma in situ
When entire thickness of epithelium is involved (top to bottom change)- no invasion has occurred=no metastasis *earliest form of cancer
28
Slaked
Fermented
29
Trismus
Lock jaw
30
BCC
Most common cancer in face and scalp, No tendency to spread, Usually 100% recovery
31
SCC
Most common cancer of oral cavity, | Epidermoid carcinoma
32
Furtherback
Greater chance of metastasizing
33
Neoplasia
New cell growth, cell exhibit uncontrolled growth | Not coordinated with growth of adjacent cells
34
Pleo
Many
35
Odont
Tooth
36
Osteoma
Benign tumors composed of mature bone tissue * mimic tori, but develop later in life * gardners syndrome, multiple osteomas
37
Osteosarcoma
Cancer of bone tissue
38
Osteolytic
Produces large irregular radiolucency in mand
39
Osteoblastic
Produces a radiolucency in mand with irregular pattern of heavy bone radiating out from the edge of sunburst pattern
40
Rhabdomyoma
Benign tumor of mature striated skeletal muscle cell origin
41
Rhabdomyosarcoma
Malignant tumor of striated skeletal muscle *primarily a childhood tumor seen in children younger than age 10
42
Leukemia
Malignancy of white blood cells
43
Lymphoma
Group of malignancies involving leukocytes (usually t and b)
44
Hodgkins lymphoma
Malignancy cancer of the lymphatic system * painless enlargement of 1 or more cervical lymph nodes * diagnosis made through exam of lymph nodes and the finding of reed sternberg cells
45
Endemic burkitts
Believed to be caused by Epstein Barr virus, 1st identified in African American children. *painless intraosseous Max lesions, can cause facial deformity, tooth mobility, and premature exfoliation of primary teeth
46
Sporadic burkitts
Believed to be caused by w chromosomal abnormality. *1st developed in American children, develop abdominal tumors with rare jaw involvement
47
Cysts are defined as
Pathological cavities of either bone or soft tissue that are lined with epithelium
48
Odontogenic cysts
Develop from epithelial tissue of dental origin or tooth forming tissue
49
Developmental or fissural cysts
Thought to form because of inclusion of epithelial tissue during the embryonic process when the facial processes fused
50
Oncogenic viruses
Tumor producing or agent with potential to cause development
51
Lymphangioma
Benign, congenital tumor present at or shortly after birth. Comprised of a slowly enlarging proliferation of lymphatic vessels
52
Hemangioma
Benign, congenital tumor seen shortly after birth * composed of a large tangle of blood vessels * most common location head and neck. * usually resolve by age 5 or 6
53
Angiosarcoma
Malignancy of blood vessels | *patients tend to be elderly and present a bruise of the scalp or forehead that does not heal.
54
Koposi syndrome
Type of Angiosarcoma that is associated with human herpes virus 8 (hhv8) * tumors benign as flat painless mascular lesions that grown into nodules. * associates with immune suppression patients
