12- Exophytic Lesion Flashcards

(49 cards)

1
Q

What are exophytic lesions?

A

They are the majority of soft connective tissue “tumors” presenting in the mouth are benign.
* they may represent growths that are reactive to an inflammatory stimulus, hamartomatous growths, or neoplasms.

Q

What is a harmartoma?

A

It is an overgrowth of mature cells & tissues which are normally presented in the affected tissue (abnormal growth of tissue in a normal location)

Q

What are the clinical findings of a peripheral giant cell granuloma?

A

Dark blue + purple nodule.

21
Q

What are the radiograph features of a peripheral giant cell granuloma?

A

May cause resorption of underlying bone.

22
Q

What are the treatments needed for a peripheral giant cell granuloma?

A
  • Surgical excision
  • Cleaning/scaling adjacent teeth
23
Q

What is ruled out if a peripheral giant cell granuloma is intraosseous?

A

hyperparathyroidism

24
Q

What is fibrous hyperplasia?

A

It is formation of fibrous connective tissue due to chronic low grade irritation.

25
How does a fibrous hyperplasia appear clinically?
It is usually seen as a pink mass.
26
What are the different names of a fibrous hyperplasia?
- Epulis fissuratum - Leaf fibroma
27
What is an epulis fissuratum?
It is a fibrous hyperplasia in context of an impinging denture
28
What is a leaf fibroma?
It is a flattened, exophytic palatal lesion found under a denture
29
What is fibroma?
A mass of collagen formed as a creative response which is often from acute or repeated trauma - cheek biting is common - forms a cycle of trauma, & further growth
30
Who is affected by fibroma? & at what age?
men + women. Around the 4th=6th decade most common, but can affect any age.
31
Where can we typically find the fibroma?
In the buccal mucosa, lip, tongue, in site predilection
32
What are the clinical appearances of Fibroma?
- They are smooth surfaces - Pink/normal colour - may be secondarily ulcerated
33
What kind of treatment is needed for fibroma?
Surgical removal
34
How can leaf fibroma's arise?
From irritation under a denture
35
Who is prone to obtain a leaf fibroma?
Females > males Older patients (with dentures) are more common.
36
Where can typically find a leaf fibroma
On the hard palate
37
What is the clinical appearance of leaf fibroma?
pink + pedunculated lesion: narrow base.
38
What are treatments needed for leaf fibroma?
Surgical removal + denture adjustments may be required.
39
In what individual can we commonly see an Epulis Fissuratum?
- Middle aged & older patients
40
Where can we commonly see Epulis Fissuratum?
On the anterior vestibule than posterior vestibule (p.37)
41
What are the clinical appearances of an Epulis Fissuratum?
Multiple folds of pink linear tissue.
42
What are the treatments needed for an Epulis Fissuratum?
Surgical removal + remake of dentures
43
What are Giant cell Fibroma?
They are like normal fibromas, BUT are NOT related to trauma or irritation.
44
Where can we commonly see giant cell fibroma?
On the gingiva.
45
How does a giant cell fibroma differ from a normal fibroma histologically?
Giant cell fibroma has the presence of LARGE fibroblasts hence "Giant Cells" (p.39)
46
What is a giant cell fibroma often mistaken for?
For a papilloma
47
What is a retrocuspid papilla?
It is a small fibrous gingival nodule (p.41)
48
Where are the retrocuspid papilla typically found on ?
Found on the lingual gingiva + behind mandibular canines (often bilateral + histologically identical to giant cell fibroma)
49
What kind of treatment is needed for a retrocuspid papilla?
No treatment required + reinforce to patient the benign nature of condition.
