Bulla

Answer 1

fluid in or under the epithelium: a large blister

Crust

Answer 2

Dried or clotted serum protein on surface of skin mucous

Question 3

Erosion

Answer 3

Superficial ulcer or laceration

Question 4

Answer 4

a circumscribed area of color change without elevation

Question 5

large palpable mass, elevated above the epithelial surface.

Question 6

Question 12

Indications for Biopsy

Answer 12

1. Leioson persists more than 2 weeks with no apparent etiologic basis
2. Inflam lesion that doesn’t respond to local treatment within 10-14 days.
3. hyperkeratotic changes in superficial tissu
4. Any persistent tumescence (swelling)
5. Inflammatory changes of unknown cause that persist
6. Lesions that interfere with local function
7. Any lesion that has the characteristics of malignancy

Question 13

Malignancy

Answer 13

rapid growth, destruction of adjacent structures, paresthesia or numbness, displacement of teeth, unexplained bleeding , pain, induration, fixation to underlying tissues
Eg. Submn lymph node

Question 14

Cytology

Answer 14

First described for detection of cervical malignancies: “pap” smear

“brush” biopsy kits available (CTX)

Some studies have found unacceptable number of false negatives

Must be examined by pathologists who have expertise in oral cytology

Doesn’t permit the pathologist to visualize histologic architecture

Question 15

Aspiration

Answer 15

A needle and syringe to penetrate a lesion for aspiration of its contents

Yields valuable information - solid, fluid, clear, purulent

ANY radiolucency in the bone should be aspirated before surgical intervention!

Material may be submitted for pathology or microbiologic evaluation

Question 16

Aspiration

Answer 16

A needle and syringe to penetrate a lesion for aspiration of its contents

Yields valuable information - solid, fluid, clear, purulent

ANY radiolucency in the bone should be aspirated before surgical intervention!

Material may be submitted for pathology or microbiologic evaluation

Question 17

Incisional Biopsy

Answer 17

If the lesion is too large to excise
without causing excess morbidity
(>1 cm or in close proximity to vital anatomic structures.)

If area appears difficult to excise

If there is a suspicion of malignancy
