Q

Most common “tumor” of the oral cavity

A

Traumatic (Irritation) Fibroma

20
Q

Traumatic (Irritation) Fibroma
* results from?
* Not a true?

A
  • Inflammatory fibrous hyperplasia
  • Not a true neoplasm of fibroblasts - a reactive lesion rather than a true neoplasm
21
Q

describe, likely dx from so far?

A

sessile mucosal colored nodule located on the buccal mucosa
Traumatic (Irritation) Fibroma

22
Q

describe, likely dx from so far?

A

sessile keratotic nodule located on the buccal mucosa
Traumatic (Irritation) Fibroma

23
Q

how can traumatic fibromas appear?

A

sessile nodules that can be keratotic or mucosal colored

24
Q

biopsy from a buccal mucosa sessile nodule

A

traumatic fibroma

25
Q

traumtic fibroma histo

A

fibroblast hyperplasia beneath typical epithelium

26
Q

Giant Cell Fibroma
* Distinct from?
* Often exhibits? mistaken for?
* can also app as?

A
  • Distinct from irritation fibroma – may not be associated with an identifiable source of chronic irritation and occurs at younger age
  • Often exhibits a papillary surface and may be clinically mistaken for papilloma
  • can also app as a papule
27
Q

describe? likely dx?

soft palpation (not bone)
A

mucosal colored nodule on the palate
likley GCF

28
Q

where could giant cell fibromas occur?

A

anywhere in the mouth

29
Q

describe? what lesion can look this way?

A

mucosal colored papillary nodule located on the lingual frenum
GCF

30
Q

describe? what could this be?

A

white papillary nodule located on the buccal mucosa
GCF

31
Q

giant cell fibroma histo

A

multinucleated fibroblasts and elongated rete pegs

32
Q

biopsy from mucosal colored papillary nodule located on the lingual frenum

A

giant cell fibroma

33
Q

what dx does this cell indicate?

A

GCF, multi-nuc fibroblast

34
Q

Epulis Fissuratum
* Synonyms
* what is it?
* Associated with?

A
  • Synonyms:
    – Inflammatory fibrous hyperplasia
    – Denture injury tumor
    – Fibrous epulis
    – Denture epulis
  • Redundant fibrous tissue
  • Associated with denture flange
35
Q
A

epulis fissuratum

36
Q

histo of epulis fissuratum

A

fibrous hyperplasia

37
Q

Inflammatory Papillary Hyperplasia
* Pathogenesis?
* tx

A
  • Denture papillomatosis
  • Poor oral hygiene combined with ill-fitting prosthesis, or keeping denture in too much
  • Surgical excision and correct prosthesis
38
Q

why does inflammatory papillary hyperplasia app red?

A

overlying candidasis infection

39
Q

how to tx inflam pap hyperplasia

A

new denture/tissue conditioner
antifungals for denture and tissue for candidasis
can also be removed prior to new prothesis

40
Q
A

inflam pap hyper

41
Q

Medication Associated Gingival Enlargement
* Enlargement begins in? and forms?
* clinical appearance?
* Multiple drugs?
* Severity is related to?

A
  • Enlargement begins in the interdental papillae and forms pseudopockets
  • Non-specific clinical appearance
  • Multiple drugs are synergistic
  • Severity is related to patient susceptibility and local factors
42
Q

how can med related ging hyper be resolved

A

cannot be reverted with hygiene, must perform gingevectomy or consult for new Rx

43
Q

common Rx of ging hyper

A
  • Anticonvulsants– Dilantin (phenytoin) – 50%
  • Calcium channel blockers– Procardia (nifedipine) – 25%
  • Immunosupressants– Sandimmune (cyclosporin) – 25%
44
Q

medication related ging hyper histo may resemble? dif how?

A

may look like GCF with elongated rete pegs but does not have multi nuc giant cells

45
Q

Drug-Related Gingival Enlargement -Treatment

A
  • Control local factors - anti-plaque agents (chlorhexidine)
  • Drug substitution
  • Drug therapy - folic acid, metronidazole, azithromycin
  • Surgical excision - gingivectomy
