non-odontogenic tumors Flashcards
idiopathic osteosclerosis
bone scar, enostosis, dense bone island and bone whorl
melanotic neuroectodermal tumor of infancy origin
ncc
where does a melanotic neuroectodermal tumor of infancy occur
ant max of infants (radiolucent)
central giant cell granuloma features
occurs in mandible
multinucleated giant cells
benign (rapid growth in aggressive)
2 types - aggressive and nonaggressive
non aggressive CGCG
asymptomatic, slowly growing, no root resorption, nor perforation, don’t recur
aggressive CGCG
pain, paresthesia, root resorption, cortical perforation, higher recurrence rate
you can see the same microscopic features of CGCG in what
hyperparathyroidism and cherubism
tx of CGCG
curettage
aggressive flesions - intralesional corticosteroids, calcitonin, interferon
3 benign fibro-osseous lesions
cemento-osseous dysplasia
ossifying fibroma
fibrous dysplasia
where does periapical cemental dysplasia happen
ant mandible
where does focal cemento-osseous dysplasia happen
one spot, anywhere but the ant mand
where does florid cemento-osseous dysplasia happen
multiple quads or sextants
t/f cemento-osseous dysplasias are neoplasms
false
t/f cemento-osseous dysplasias need to be removed
false
tx for pa cemento-osseous dysplasia
none
pa and florid -osseous dysplasia is common in what race
middle aged female african americans
focal cemento-osseous dysplasia is common in what race
caucasians
t/f fibrous dysplasia is a gene mutation
true. the severity depends on when the mutation took place
t/f monostotic fibrous dysplasia happens when the gene mutation happened later in development
true. involves 1 bone, usually the maxilla
2 syndromes associated with polyostotic dysplasia
jaffe and mccune albright syndrome
fibrous dysplasia looks like what on a radiograph
“ground glass”/fuzzy homogenous radiopacity
increased trabecular pattern
expansion
margins blend into surrounding bone
tx for fibrous dysplasia
surgical recontouring
t/f fibrous dysplasia lesions should be irratiated
false. it may cause malignant transformation
central ossifying fibroma
same thing as a central ossifying-cementifying fibroma
true neoplasm of bone
grows slowly, displaces teeth
tx for ossiyfing fibroma
enucleation and curettage
t/f hemangioma is always on your differential (unless its calcified)
true
t/f must aspirate bony lesions before pbiopsy
true
multiple osteomas are representative of
garners syndrome
the most common malignancies in the jaws are primary or metastatic
metastatic
primary cancers of the jaw
osteosarcoma, chondrosarcoma, ewings sarcoma, multiple myeloma, lymphoma, odontogenic carcinoma
sun ray appearance is a feature of
osteosarcoma
can be radiopaque, radiolucent, or mixed
tx for osteosarcoma
radical surgery
dependent on where it is (mand can just cut it out, max is more difficult)
radiographic features of chondrosarcoma
radiolucent,radiopaque, or mixed
poorly defined margins
root resorption
thinning of cortical bone
ewings sarcoma
neuroectodermal origin tumor of bone
clinical features of ewings
mainly in children or young adults
pain swelling
radiographic features of ewings
onion peel periosteum
pooly defined radiolucent border
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
radiographic appearance of multiple myeloma
punched out appearance
bence jones (M proteins) proteins are found in
multiple myeloma
multiple myeloma tx
chemo
most common malignancies that metastasize to the jaws
BLTKCP
BLT with a kosher pickle
breat, lung, thyroid, kidney, prostate, colorectal
