Flashcards in non-odontogenic tumors Deck (41):
1

idiopathic osteosclerosis

bone scar, enostosis, dense bone island and bone whorl

2

melanotic neuroectodermal tumor of infancy origin

ncc

3

where does a melanotic neuroectodermal tumor of infancy occur

ant max of infants (radiolucent)

4

central giant cell granuloma features

occurs in mandible
multinucleated giant cells
benign (rapid growth in aggressive)
2 types - aggressive and nonaggressive

5

non aggressive CGCG

asymptomatic, slowly growing, no root resorption, nor perforation, don't recur

6

aggressive CGCG

pain, paresthesia, root resorption, cortical perforation, higher recurrence rate

7

you can see the same microscopic features of CGCG in what

hyperparathyroidism and cherubism

8

tx of CGCG

curettage
aggressive flesions - intralesional corticosteroids, calcitonin, interferon

9

3 benign fibro-osseous lesions

cemento-osseous dysplasia
ossifying fibroma
fibrous dysplasia

10

where does periapical cemental dysplasia happen

ant mandible

11

where does focal cemento-osseous dysplasia happen

one spot, anywhere but the ant mand

12

where does florid cemento-osseous dysplasia happen

multiple quads or sextants

13

t/f cemento-osseous dysplasias are neoplasms

false

14

t/f cemento-osseous dysplasias need to be removed

false

15

tx for pa cemento-osseous dysplasia

none

16

pa and florid -osseous dysplasia is common in what race

middle aged female african americans

17

focal cemento-osseous dysplasia is common in what race

caucasians

18

t/f fibrous dysplasia is a gene mutation

true. the severity depends on when the mutation took place

19

t/f monostotic fibrous dysplasia happens when the gene mutation happened later in development

true. involves 1 bone, usually the maxilla

20

2 syndromes associated with polyostotic dysplasia

jaffe and mccune albright syndrome

21

fibrous dysplasia looks like what on a radiograph

"ground glass"/fuzzy homogenous radiopacity
increased trabecular pattern
expansion
margins blend into surrounding bone

22

tx for fibrous dysplasia

surgical recontouring

23

t/f fibrous dysplasia lesions should be irratiated

false. it may cause malignant transformation

24

central ossifying fibroma

same thing as a central ossifying-cementifying fibroma
true neoplasm of bone
grows slowly, displaces teeth

25

tx for ossiyfing fibroma

enucleation and curettage

26

t/f hemangioma is always on your differential (unless its calcified)

true

27

t/f must aspirate bony lesions before pbiopsy

true

28

multiple osteomas are representative of

garners syndrome

29

the most common malignancies in the jaws are primary or metastatic

metastatic

30

primary cancers of the jaw

osteosarcoma, chondrosarcoma, ewings sarcoma, multiple myeloma, lymphoma, odontogenic carcinoma

31

sun ray appearance is a feature of

osteosarcoma
can be radiopaque, radiolucent, or mixed

32

tx for osteosarcoma

radical surgery
dependent on where it is (mand can just cut it out, max is more difficult)

33

radiographic features of chondrosarcoma

radiolucent,radiopaque, or mixed
poorly defined margins
root resorption
thinning of cortical bone

34

ewings sarcoma

neuroectodermal origin tumor of bone

35

clinical features of ewings

mainly in children or young adults
pain swelling

36

radiographic features of ewings

onion peel periosteum
pooly defined radiolucent border

37

clinical features of multiple myeloma

rare, before 40
bone pain in the back
most common in axial skeleton (vert, ribs, skull, pelvis)
pathological fractures
fatigue
fever

38

radiographic appearance of multiple myeloma

punched out appearance

39

bence jones (M proteins) proteins are found in

multiple myeloma

40

multiple myeloma tx

chemo

41

most common malignancies that metastasize to the jaws

BLTKCP
BLT with a kosher pickle
breat, lung, thyroid, kidney, prostate, colorectal
