16
Q

What is the treatment of Lichen Planus?

A

asymptomatic= nothing
lesions= 0.05% flucinonide gel and clotrimazole 10 mg

17
Q

What is common in Pemphigoid?

A

cutaneous, separation between epithelium and connective tissue junction

18
Q

What’s the difference between bollous and cicatricial pemphigoid?

A

bollous= no scarring
cicatricial= scarring

19
Q

How common is pemphigoid in oral lesions?

A

40%

20
Q

What can you see in immunofluorescence in pemphigoid?

A

immunoglobulin G. complement 3, sometimes other immunoglobulins, fibrin deposits

21
Q

What is the treatment for pemphigoid?

A

corticosteroids (prednisone) and immunomodulator drugs

22
Q

Where can cicatrical/mucous membrane pemphigoid affect?

A

anywhere there is mucous a membrane

23
Q

What is symblepharon?

A

scarring resulting in adhesion between eyelid and eyeball seen in cicatrical/mucous membrane

24
Q

What is ankyloblepharon?

A

scarring resulting in adhesion at edges of eyelids

25
Q

How long is the cycle of pemphigoid oral lesion?

A

the bullae take 2-3 days to rupture after forming which then leave an ulceration
healing takes 3 or more weeks

26
Q

What is the treatment of pemphigoid oral lesion?

A

0.05% fluocinonide gel and clobetasol propionate

27
Q

What is the difference in separation between pemphigoid and pemphigus vulgaris?

A

pemphigoid= separates between epithelium and connective tissue (sub epithelial)
pemphigus vulgaris= separates between the 2 epithelial layers
(intra epithelial)

erythema multiform can be intra or sub epithelial

28
Q

What is etiology of pemphigus vulgaris?

A
  • antibiotics and other drugs
  • autoantibody to cadherin-type epithelial cell adhesion molecules
29
Q

What is most often involved in the oral cavity for pemphigus vulgaris?

A

soft palate (80%)
then buccal mucosa (46%) , then tongue (20%) , then lower labia mucosa (10%)

30
Q

What are key identifiers for pemphigus vulgaris?

A
  • “tombstone” appearance in histopath
  • strawberry gingivitis
  • intra epithelial
31
Q

What do you give to treat chronic ulcerative stomatitis?

A

hydroxychloroquine because it’s not responsive to corticosteroid treatment

32
Q

What are the clinical presentations of lupus erythematosis?

A

systemic, chronic, and cutaneous

lesions are similar to lichen planus

33
Q

What is a key feature in erythema multiform?

A

target/iris lesion

34
Q

What is the later form of erythema multiform?

A

Stevens-Johnson syndrome which effects every mucosa of your body

35
Q

What is etiology of erythema multiform?

A

unknown but thought to be caused by cytotoxic immune reaction

36
Q

What is the histopathology of erythema multiform?

A

can be sub or intra epithelial

37
Q

What is the treatment of erythema multiform?

A

antihistamines, topical anesthetics (for pain), plaque control, systemic corticosteroids
