Presentation Transcript
OSTEOBLASTOMA & OSTEOID OSTEOMA
CLINICAL FEATURES mandible, poeterior Female, <30 2-4 cm Osteoblastoma pain, tenderness, swelling Aspirin Well or ill radiolucency with patchy mineralization reactive sclerosis Aggressive osteoblastoma: larger, sever pain <2 cm pain, nocturnal osteoid osteoma Aspirin Well radiolucency Reactive sclerosis target
HISTOPATHOLOGY Mineralized material, reversal lines Osteoclast Osteoblast, hyperchromatic Loose connective tissue
TREATMENT & PROGNOSIS Local excision Good prognosis Uncommon recurrence Rare osteosarcoma Aggressive osteoblastoma:50% recurrence
CEMENTOBLASTOMA Odontogenic neoplasm of cementoblasts
CLINICAL FEATURES Rare Mandible, molar & premolar(50% 6) Children & young adults 2/3 pain , swelling Some: exp. , erosion, infiltration into the pulp Radiopaque mass with a thin radiolucent rim Obscured outline of the root
HISTOPATHOLOGY Resemble osteoblastoma Thick trabeculae of mineralized material with blast-like rim Basophilic reversal line Uncalcified matrix( radiolucent zone)
TREATMENT & PROGNOSIS Ext . Of the tooth with mass Root amputation
CHONDROMA Benign tumor of cartilage Hands and foot In the jaws: many recurred & acted in malignant manner Arise from vestigial cartilaginous: anterior maxilla, symphysis, coronoid, condyle
CLINICAL FEATURES 3rd, 4thdecade Condyle , anterior maxilla Painless, slow growing Radiolucency with central area of radiopacity Single Multiple: Ollier disease, Maffucci syndrome
HISTOPATHOLOGY circumscribed mass of mature cartilage well formed lacunae, small chondrocytes
TREATMENT & PROGNOSIS Should be Considered as potential chondrosarcoma Total surgical removal
DESMOPLASTIC FIBROMA Uncommon tumor of fibroblastic origin Soft tissue fibromatosis Tuberous sclerosis
CLINICAL FEATURES <30 years Mandible, Femur, pelvice bones Molar angle-ascending ramus Painless swelling Multi or unilocular radiolucent area Thin cortex Rare cortical reaction Soft tissue mass
HISTOPATHOLOGY Small elongated fibroblasts & collagen, tipical, no mitoses Bone spicules
TREATMENT & PROGNOSIS Benign Locally aggressive, bone destruction, soft tissue extension Radical surgery
OSTEOSARCOMA Definition Most common malignancy
CLINICAL FEATURES Paget & irradiation Extragnathic bimodal Jaw 3rd& 4th Male max = man * Swelling & pain
RADIOGRAPHY Ill defined Spiking Sunburst Codman s triangle Widening of PDL
HISTOPATHOLOGY Microscopic criteria Common Types Low grade well dif
TREATMENT & PROGNOSIS jaws: less aggressive, low grade Most important indicator Metastase lung & brain Man, Max Usual cause of death
JUXTACORTICAL OSTEOSARCOMA
Parosteal pedanculated no elevation & reaction Low grade Inadequate surgery ? sessile Periosteal extend to the soft tissue chondroblastic treatment prognosis
POSTIRRADIATION BONE SARCOMA 3-14 years after radiation Dose Osteosarcoma, fibrosarcoma, chondrosarcoma prognosis
