Q

When u call an ulcer an ulcer?

A

If you just scratch your skin, this is only peeling of the skin not an ulcer I have to see the deemis and exposed CT to call it an ulcer

Q

What causes the area of discoloration in a macule?

A
  1. It could be due to the presence of vascular lesion or inflammation
  2. Pigmented due to the presence of melanin or drugs

Q

What is the importance of a papule to be circumscribed?

Means that I can trace the outline and it is an important sign of a benign lesion

Q

If the papule is diffused could it be maliganant?

A

If it is diffuse, meaning all over the place, it doesnt necessarily mean that its maliganant ( it may be maligant)

20
Q

Ulcer

A

Is loss of epidermis
It may bleed

If u just scratch your skin, this is only peeling of the skin not an ulcer
I have to see the dermis and exposed CT to call it an ulcer

21
Q

Describe an ulcer

A

There is a white boarder around it that could be keratosis

22
Q

What is the partial loss of surface epithelium without exposure of underlying connective tissue

A

Erosion

23
Q

It is like a scratch —> so, if you take your fingernail and scratch the upper area of your mouth, you can peel off the mucosa

So, it is not exposing the CT

Some patients induce those lesions to get attention, so they take a sharp instrument/ nail and injure the mucosa (self induced)

A

Erosion

24
Q

Is loss of a part of the epidermis
Moist surface

A

Erosion

25
Q

Moist red lesion
It is a superficial defect of epithelium associated with partial loss of epidermis

A

Erosion

26
Q

Circumscribed accumulation of fluid within or below epithelium, less than 5 mm in diameter

A

Vesicle

27
Q

Is a fluid filled blister like when you get a burn, u get a blister

A

When its small —> vesicle
When its bigger —> bulla

28
Q

Elevated blisters containing clear fluid that are less than 1 cm in a diameter

A

Vesicles

29
Q

Circumscribed accumulation of fluid within or bellow epithelium —> larger than 5 mm in diameter

A

Bullae

30
Q

What happens to the bullae or vesicles once the patient comes to the clinic?

A

By the time patient coming to the clinic the vesicle or bulla are ruptured, so u diagnose it by taking history

31
Q

Elevated area contain pus

A

Pustule

32
Q

Elevated blister like lesion containg pus

A

Pustule

33
Q

A blind ended, usually epithelial lined track

A

Sinus

34
Q

Only opening of one end

A

Sinus

35
Q

An epithelial tract running between two epithelial surfaces, e.g. mouth to maxillary antrum

A

Fistula

36
Q

What is the oro-antral fistula?

A

Is a connection between the maxillary antrum (maxillary sinus) and the mouth

37
Q

Can u as a student , cause an oro-antral fistula for a patient (iatrogenic)?

A

Yes, by accident when extracting premolars or molars of the upper arch using the wrong technique - you will try to push it up ( you should pull it downwards) and it will go into the antrum.
If you made this communication, the patient will not know, but you can easily find out by asking the patient to talk, and the patient will sound different ( nasal twang)

38
Q

It has opening from 2 ends

A

Fistula

39
Q

What is a characteristic of oral ulcers?

A

They are usually painful

40
Q

Oral ulcers are usually painfull except

A

The only exception is squamous cell carcinoma
(Malignant ulcers maybe initially painless)

41
Q

When is a biopsy for oral ulceration is a must?

A

Biopsy is a must for any ulcer that does not respond to treatment or persists for more than 2 to 3 weeks

Note: it varies between patients
This is a general rule, but if u are suspicious, dont wait 2-3 weeks and take a biospy even if its the first day

42
Q

What are the causes of mouth ulcers?

A
  1. Maliganant ulcers
  2. Infective
  3. Associated with systemic disease
  4. Associated with deematological disease
  5. Iatrogenic
  6. Idiopathic
  7. Truamatic
  8. Developmental
43
Q

What is a developmental cause of oral ulceration?

A

Epidermolysis bullosa

44
Q

What are traumatic causes of oral ulceration?

A
  1. Mechanical —> tongue bite
  2. Thermal —> pizza burn
  3. Chemical —> aspirin burn
  4. Factitious —> self-inflicted trauma
  5. Radiation
  6. Traumatic granuloma
45

Associated with dermatological disease?

A
  1. Lichan planus —> erosive lichan planus
  2. Lupus erythromatosis —> discoid lupus erytgematosus / systemic lupus erytgmatosus
  3. Vesiculobullous disease —> pemphigoid pemphigus
