Category:
-Neoplastic
Etiology:
-Benign neoplasm derived from Schwann cells
Demographics:
-Female predilection
-Rare in children
Clinical Presentation:
-Sessile submucosal nodule
-Pink, sometimes with yellow hue
-Dorsal tongue most common oral site
Diagnosis:
-Biopsy
Tx:
-Excisional biopsy

Category:
-Neoplastic
Etiology:
-Benign tumor of fate
Demographics:
-Uncommon in children
Clinical Presentation:
-Soft, smooth-surfaced nodule
-Usually yellow, sometimes pink
-Buccal mucosa and buccal vestibule most common oral sites
Diagnosis:
-Biopsy
Tx:
-Excisional biopsy
Hemangioma
-Category
-Etiology
-Demographics
-Clinical Presentation
-Diagnosis
-Tx
Category:
-Neoplastic
Etiology:
-Benign vascular tumor
Demographics:
-Most common tumor of infancy
Clinical Presentation:
-Bright red to dull blue/purple nodule
-60% in head and neck
-More common in females
-Undergo rapid growth for 6-12months, then involute
-90% resolve by age 9
Diagnosis:
-Biopsy
Tx:
-Varies depending on subtype, location and size
Vascular Malformation
-Category
-Etiology
-Demographics
-Clinical Presentation
-Diagnosis
-Tx
Category:
-Developmental
Etiology:
-Structural anomaly of blood vessels
Demographics:
-Present at birth but persist (and may become more apparent) throughout life
Clinical Presentation:
-Can vary from pink/red macule to blue/purple mass
-Presentation varies based on kind of vasculature involved (capillary, venous, arteriovenous)
-Port wine stains (capillary malformations) common on the face
Diagnosis:
-Aspiration (can confirm vascular origin)
-Imaging (angiogram)
-Biopsy
Tx:
-Varies depending on subtype, location and size
Describe Diascopy
-Helpful clinical test
-Use a glass slide to compress a lesion you think may be vascular
-Vascular lesions tend to blanch with pressure (blood is displaced and lesion returns to normal color)
**Not all vascular things will blanch, but if it does, it’s for sure vascular
Neurofibroma
-Mesenchymal tumor
-Benign
-Nerve origin
-Can occur in many parts of the body
-Tongue and buccal mucosa common oral sites
-Treated with excisional biopsy
Schwannoma
-Mesenchymal tumor
-Benign
-Nerve origin
-Tongue most common oral site
-Treated with excisional biopsy
What are the specific trends for salivary gland tumors?
Major Glands
-The larger the gland, the more likely it is to be benign
-The smaller the gland, the more likely it is to be malignant
Minor Glands
-Almost 50/50 chance of being malignant
Describe salivary gland tumors
-Benign or malignant
-Affect major or minor salivary glands
-Common sites for minor salivary gland neoplasms:
1. Hard palate (most common)
2. Soft palate
3. Upper lip
List the 4 most common salivary gland tumors
- Pleomorphic adenoma
- Mucoepidermoid carcinoma
- Polymorphous adenocarcinoma
- Adenoid cystic carcinoma
Pleomorphic Adenoma
-Salivary gland tumor
-Benign
-Most common salivary gland neoplasm
-Can recur
Mucoepidermoid Carcinoma
-Salivary gland tumor
-Malignant
-Most common salivary gland malignancy
-Usually low-grade
Polymorphous Adenocarcinoma
-Salivary gland tumor
-Malignant
-Usually low-grade
-Not found in major salivary glands)
Adenoid Cystic Carcinoma
-Salivary gland tumor
-Malignant
-More aggressive (perineural invasion)
Describe the treatment for salivary gland tumors
-Varies depending on benign vs. malignant, location, histopathologic grade, and clinical stage
-Local surgical excision, wide surgical excision, superficial parotidectomy, or total gland removal with or without neck dissection
