Pyogenic granulomas and Peripheral giant cell granulomas are similar but can be distinguished by color. What color denotes which?

A

Peripheral GC Granuloma –> Blue-Purple

Pyogenic granuloma –> Bright red

28
Q

Does the Peripheral Giant Cell Granuloma only occur on soft tissue?

A

It develops within the soft tissue but may produce cupping respiration of underlying bone.

29
Q

Treatment of Peripheral Giant Cell Granuloma

A

Excision and removal of irritants, may recur

30
Q

Define Pyogenic Granuloma

A

Reactive lesion representing hyperplasia of body’s basic reparative tissue - granulation tissue
- thought to represent an exuberant tissue response to local irritation or trauma

31
Q

Clinical Features of Pyogenic Granuloma

A

Reddish
Ulcerated
Pedunculate or sessile mass
Asymptomatic but may bleed easily

32
Q

Where is a pyogenic granuloma most likely to occur?

75% of cases on gingiva

Can occur anywhere including the skin

33
Q

What age is a pyogenic granuloma most common?

A

2-4 decades

- Children and young adults

34
Q

What sex is pyogenic granulomas most common?

A

Females, often in pregnancy “pregnancy tumor”

35
Q

True or False, pyogenic granuloma are uncommon to be found in extraction sockets/

A

False, Not uncommon in extraction sockets - epulis granulomatosa

36
Q

Histologic features of Pyogenic granuloma

A

Hyperplastic granulation tissue, fibroblasts with delicate collagen
Endothelial cells + capillaries and dilated larger vessels

37
Q

Treatment for Pyogenic granuloma

A

Excision and removal of irritants

May recur

38
Q

Parulis “Gum Boil” description

A

Represents draining from a source of odontogenic infection of either pulpal or periodontal origin

  • Pus (purulence, suppuration) = Bacterial infection
39
Q

Define Localized Juvenile Spongiotic gingival hyperplasia

A

Localized hyperplasia presumably from externalized sulcular epithelium on gingiva

40
Q

A

Almost exclusively 1-2 decades

41
Q

What sex is Localized Juvenile Spongiotic gingival hyperplasia normally found in?

A

Female 2:1

42
Q

What location is Localized Juvenile Spongiotic gingival hyperplasia normally found?

A

Red often papillary gingival lesions

44
Q

Histology features of Localized Juvenile Spongiotic gingival hyperplasia

Papillary proliferation of inflamed epithelium with intercellular edema (Spongiosis)

45
Q

Treatment of Localized Juvenile Spongiotic gingival hyperplasia

A

Excision

46
Q

Define Hemangioma

A

Overgrowth of blood vessels

- Hamartoma –> localized overgrowth of tissues native to the part, often developmental

47
Q

Clinical characteristics of Hemangioma

A
  • Rapid proliferation of endothelial cells at birth or shortly thereafter, Characteristically involute
  • Reddish to purple mass lesions that tend to blanch with pressure
  • can occur in bone, often multilocular or soap bubble appearance (why you aspirate before bone biopsy)
