cysts.
Patient with multiple
osteoma
must always be sent for colonoscopy.

Osteoblatoma
Osteoblasts
Mandible > Maxilla
Excision or curettage.
Risk of Osteosarcoma.

chemoradio
Slide9Osteosarcoma
Clinical Features
Only 5–10% in head and neck; mostly in jaws
Usually painless swelling in jaws
Mandible slight predominance
Males slight predominance
May occur in any age group; peak in fourth decade
Prognosis of jaw sarcoma is poor
Slide10SUN RAY
Slide11Slide12Slide13Malignant Tumors
Chondrosarcoma
Maxilla
Pain, swelling, teeth loosening
Wide Excision
Slide14Chondrosarcoma
Clinical Features
Mostly in adults in fourth to sixth decades
Mainly affect long bones.
Less aggressive, more slowly growing than osteosarcoma
Better prognosis; metastasizes more seldom than osteosarcoma
Mandible and maxilla, but rare 1-12% of all
Chondrosarcomas
.
Slide15Slide16Slide17Malignant Tumors
Ewing’s Sarcoma
Below 20 years
Pain and swelling
Parasthesia
Surgery+chemo+radio
Good prognosis
Slide18Ewing Sarcoma
Clinical Features
Only 1–4% in head and neck area; most commonly mandible
Hard swelling, pain or pain-free
Males more frequent than females
Usually first and second decades, but may occur at any age
Slide19Slide20Slide21Slide22Slide23Multiple Myeloma
Clinical Features (Myeloma)
Most common primary bone malignancy in adults
Males more frequent than females
Older age groups (50 years)
Bone pain, malaise
Clinically, it presents with bone swelling, tooth mobility, pain, and
paresthesia
Slide24Slide25Langerhans Cells Histocytosis
Langerhans cell
histiocytosis
(
LCH
) is a disease of unknown

, characterized by proliferation of pathological Langerhans cells within different organs
Slide26Langerhans Cells Histocytosis
4 Main types
Solitary
