Answer 2

1. Port wine stain (capillaries)

3. arteriovenous malformation (bruit, thrill)

Question 3

T/F: vascular malformation grows proportionately with the patient

true

Question 4

why is it important to distinguish that vascular malformations grow with the patient?

Answer 8

blood within vessels with be pushed into adjacent vessels and lesion will blanch

Question 9

when may a diascopy be helpful?

Answer 9

may be helpful in determining whether a red lesion is due to extravasated blood or to blood that is contained within vessels

Question 10

T/F: vascular malformation are pathognomonic

Answer 10

false, is NOT

several conditions can blanch including periodontal disease

Question 11

oral considerations with port wine stain

Answer 11

1. hemorrhage may be encountered

2. lasers may be helpful in removing hyperplastic lesions

Question 12

why might hemorrhage be encountered with port wine stain?

Answer 12

1. flossing and dental prophylaxis may be difficult
