Q

What is the most common place to see a hemangioma?

A

On teh head and neck area.
Most common intraoral area would be the tongue

24
Q

What would a hemangioma look like clinically?

A

Since it is vascularly derived it would have a bluish-purplish hue and is often raised

25
Q

Lymphangioma is a benign tumor of what vessel?

A

The lymphatic vessels

26
Q

Name a laignant vascular tumor often associated w/ HIV patients?

A

Kaposi sarcoma

27
Q

What is a common used name for a melanotic nevi?

A

Mole

28
Q

Why is it important to document the color, size and shape of a mole?

A

Any type of change could indicate a malignant verion or a melanoma

29
Q

What are the tumors of bone and cartilage?

A

Osteoma
Osteosarcoma
Tumors of cartilage

30
Q

What is an osteoma?

A
  • Asymptomatic, benign tumor composed of benign compact bone
  • Component of Gardner Syndrome
31
Q

What is osteosarcoma?

A
  • Bone cancer that begins in the cells that form bones
  • Malignant tumor of bone forming tissue
  • Most common primary malignant tumor of bone in pts less than 40 years old
  • Twice as frequent in mandible than maxilla
  • More common in men
  • Radiographically: Destructive, poorly defined lesion. Sunburst pattern

5 year life expectancy in 20% of pts

32
Q

Tumors of cartilage

A

Chondroma= benin tumor of cartilage
Chondrosarcoma= malignant tumor of cartilage

5 year life expectancy in 30% of pts

33
Q

Tumors of blood forming tissues

A
  • Leukemia
  • Lymphoma
  • Multiple myeloma
34
Q

Characteristics of leukemia

A

Acute most common in children and young adults
* Is a proliferation of immature white blood cells

Chronic most common in middle-aged adults
* Proliferation of mature white blood cells

35
Q

What is lymphoma (non-hodgkins lymphoma)?

A
  • Malignant tyumor of lymphoid tissue
  • Presents as gradual enlargement of lymph nodes
  • Most common intraorally on the tonsils
  • Usually in adults and more common in men
36
Q

What is multiple myeloma?

A
  • Systematic, malignant proliferation of plasma cells (healthy ones help you fight infection by making antibodies that recognize and attack germs)
  • Mandible more often affected than maxilla
  • Very poor prognosis
37
Q

What is the most frequent intraoral site for a metastatic tumor? How does it appear radiogrphically?

A
  • The mandible
  • Lesions are usually poorly defined and radiolucent
  • Prognosis for people with tumors in the jaw is poor
