Epithelial st masses arise from epithelium where as mesenchymal st masses arise from ______ _____.
Connective tissue
What is the difference between Epithelial and Mesenchymal lesions?
Mesenchymal is a mass under normal appearing epithelium so it will often be smooth whereas epithelial will usually be smooth, rough, or papillary.
Name the Lesion
Reactive hyperplasia of fibrous tissue in response to trauma. It is the most common tumor of the oral cavity although it is not really a tumor. Pink nodule similar to color to surrounding mucosa. Sessile or pedunculated.
Fibroma
Name the Lesion
Etiology of this lesion is uncertain but thought to be a reactive process. Nodule red/pink mass. May have an ulcerated surface.
Peripheral ossifying Fibroma
Name the Lesion
Exuberant tissue response to local irritation, poor hygiene, or hormonal factors. Smooth or lobulate red/pink/purple mass. Surface is often ulcerated. Can show rapid growth.
Pyogenic Granuloma
What ST Injury lesion can show rapid growth?
Pyogenic granuloma
Name the lesion
Reactive lesion caused by local irritation/trauma.
Red/blue nodular mass
May produce ““cupping”” resorption of alveolar bone.
Peripheral giant cell granuloma
Name the lesion
Tumor-like hyperplasia of inflamed fibrous CT often secondary to ill fitting denture. Firm fold(s) of hyperplastic tissue
Can be pedunculated (leaf-like) or nodular
Inflammatory Fibrous Hyperplasia.
Inflammatory Fibrous Hyperplasia: Tumor like hyperplasia of inflamed ______ _____ _____ often secondary to ill fitting denture. ____ fold(s) of hyperplastic tissue
Can be ________ (leaf-like) or nodular.
Fibrous Connective tissue
Firm
pedunculated
Name the lesion:
Rupture of salivary gland duct and spillage of mucin
Mucocele
Name the lesion
Dome-shaped swelling
Often bluish hue
Fluctuant to firm texture
Can rupture, release fluid, and recur. Spillage of mucin. To tx need to remove feeding salivary glands.
Mucocele
Name the lesion
Mucocele occuring on the floor of the mouth
Ranula
Name the lesion
Deposition of calcium salts around nidus of debris in salivary duct.
Sialoth
Sialoth: Deposition of _____ _______around nidus of debris in salivary duct
calcium salts
Name the lesion:
Hard submucosal mass
Radiopaque mass on radiograph
Can cause episodic pain - especially when eating do to salivary duct pressure
Sialoth
What is the most common site to find fibroma?
Buccal and labial mucosa, tongue, and gingiva
What two ST injuries occur exclusively on the gingiva
- Peripheral ossifying Fibroma
- Peripheral Giant Cell Granuloma -
What is the most common site to find pyogenic granuloma
Gingiva most common oral site
Buccal mucosa, tongue, and lips
What is the most common site to find Inflammatory Fibrous Hyperplasia?
Most often in alveolar vestibule but can be on palate, etc.
What is the most common site to find Mucocele
Lower labial mucosa
What is the most common site to find Sialoth
Most common in submandibular gland duct system but can be anywhere
where salivary duct ( upper lip or buccal mucosa)
Name the demographics for these 4 Lesions
1. Fibroma
2. Peripheral ossifying fibroma
3. Pyogenic granuloma
4. Peripheral giant cell granuloma
- Fibroma - BROAD
- Peripheral ossifying fibroma -
Teenagers/Young adults
Females - Pyogenic granuloma -
Children/young adults
Females
Pregnant women - Peripheral giant cell granuloma - BROAD
Name the demographics for Inflammatory Fibrous Hyperplasia
“Middle Aged older adults
Denture wearers”
Name the demographics for Mucocele and Ranula.
Children and young adults
Name the demographics for Sialoth
Young and middle-aged adults
How to diagnose injury ST Masses?
Biopsy
Except: sialoth will be diangosed by clincal and radiographic presentation
How to tx ST injuries?
The 4 P’s -
The 4 P’s - Excisional Biopsy
Remember to all remove local irritants (plaque/calculus) for the 3 real Ps b/c tendency to recur need to go all the way down to base (bone)
T/F It is okay to wait to remove pyogenic granuloma in pregnant women because of their tendency to recur.
True
How to tx ST injuries?
Inflammatory Fibrous Hyperplasia -
Excisional biopsy
Remove source of irritation
How to tx ST injuries?
Mucocele -
Ranula -
Mucocele - Excisional biopsy, need to remove feeding salivary glands also can heal spontaneously
Ranula - Generally coming from the submandibular gland so sometime tx involves removing part of it to prevent recurrence
T/F Mucocele can heal spontaneously.
True
How to tx ST injuries?
Sialoth -
If small and round - Massage out of duct or stimulate salivary flow and apply moist heat
If large- Surgical intervention
Where do mucoceles not occur?
Dorsal surface of tongue
anterior hard palate
gingiva
Don’t occur where there are NO salivary glands
What can mimic a mucocele?
Neoplasms
