Osd5: Malignant Lesions Tetradis

Front 1

SCC
C
R

Back 1

-lip, tongue, gingiva,mucosa
-peripheral inavsion from soft tissues to bone: gingiva, retromolar pad, FOM

-irreuglar
-lucent
-ill defined, irregular borders-crater like(may have well defined border)
-minimal displacement expansion of PDL
-hyperostotic,ragged radiopacities, opacification/destruction of sinus, floating teeth

Front 2

Metastatic Carcinoma
-B

Back 2

-central(start from bone, dissmeniate from else where)

-premolar-molar mandible
-irregular
-mixed/lucent
-ill defined, irregular borders(sometime swell defined)
-destruction of LD, loosening teeth, minimal displacement
-multiple lesions, bone production from metastases

Front 3

Osteosarcoma
-B
-R
-H

Back 3

-Early
-widening of PDL/lucency around teeth-->loosening

-irregular
-ostelytic(lucent), osteoblastic(opaque), mixed, foci
-ill defined borders
-expansion, perforation
-elevation of periostem, sunray(spicules)

-bad bone bad cells

Front 4

Malignant tumors of salivary glands
-types?
-radio?

Back 4

-mucoepidermoid, adenocarcinoma, adenocystic, acidic cell , malignant mixed

-typical malignant nature
-mucoepidermoid:
-uni-multilocualr lucency
-well defined margins

Front 5

Leukemia
-clinical?

Back 5

-perio disease
-gingival infiltration/swelling
-destruction of alveolar bone
-loss of LD/loosening of teeth

-ill defined radiolucencies
-expansion
-periosteal rxn

Front 6

Burkitts Lymphoma
-

Back 6

-molar area
-single/multiple unilocular-->coealsce large multilocular
-lucent foci-mixed
-ill defined,irregular borders
-expansion, loosening/displace/premature eruption of teeth, erosion/perforation/destruction

Front 7

multiple Myeloma

Back 7

-mandible
-unilocular
-lucent
-well defined non corticated
-multiple punched out defect
-mobility/migration of teeth, fracture, skull
