2. Squamous Cell Carcinoma
Synonyms: Epidermoid carcinoma
Clinical Features
Most common malignancy of oral cavity
Males more frequent than females
Older age groups (50 years and older), but also younger than 30 years
Most frequent in tongue,floor of mouth,mandibular gingiva; retromolar trigone, and anterior tonsillar pillar, soft palate

3. Clinical photograph shows leukoplakia that transformed to gingival cancer
Intraoral panoramic view shows diffuse bone destruction

4. Coronal CT image
Coronal T2- fat suppressed MRI
Squamous cell carcinoma, maxilla; 70-year-old female with some bleeding from tender soft tissue mass of right gingival mucosa.

5. Mucoepidermoid Carcinoma
Clinical Features
Swelling with or without pain
Mandible, posterior regions, more frequent than maxilla
Females more frequent than males (unlike most oral carcinomas)
Fourth and fifth decades, but may occur in any age group
Spread to regional lymph nodes in less than 10%

6. Panoramic view
Axial CT image
Coronal CT image
Coronal T1-weighted post-Gd MRI

7. Adenoid Cystic Carcinoma
Clinical Features
Most commonly seen in minor salivary glands of head and neck, usually palate.
Mostly as a painless mass, slowly growing
Unlike most carcinomas, seldom metastasizes to regional lymph nodes
Lung most common site of metastasis
Perineural spread in more than 50%; frequent distant metastasis
Slight female predominance
Fourth to sixth decades

8. Axial CT image
Axial T2-weighted MRI
Coronal T1-weighted pre-Gd MRI
Coronal T1-weighted post-Gd

10. Non-Hodgkin’s Lymphoma
Clinical Features
Non-Hodgkin’s lymphoma of extranodal sites (as opposed to Hodgkin’s lymphoma which is predominantly nodal)
Extranodal involvement may include maxillary sinus and maxilla or, less frequently, mandible
All age groups, adults in particular
Burkitt’s lymphoma affects children; shows
rapid growth and may involve one or both jaws

11. Non-Hodgkin’s lymphoma, maxilla; 49-year-old male painless swelling

12. Multiple Myeloma Clinical Features (Myeloma)
Most common primary bone malignancy in adults
Males more frequent than females
Older age groups (50 years)
Bone pain, malaise
Plasmacytoma is a solitary form of myeloma

14. Osteosarcoma 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

17. Chondrosarcoma Clinical Features
Mostly in adults in fourth to sixth decades
Less aggressive, more slowly growing than osteosarcoma
Better prognosis; metastasizes more seldom than osteosarcoma
Mandible and maxilla, but rare

19. Ewing 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
