Salivary Gland Pathology Flashcards
Most common site for SUPERFICIAL mucoceles
Posterior buccal mucosa
Most common site and age for mucoceles
- lower lip mucosa
- children and young adults (due to trauma)
Histology:
Sub-mucosal spilled mucin surrounded by granulation tissue response. Minor salivary glands often visible adjacent to lesion.
Mucocele
Mucocele that dissects the mylohyoid muscle and causes cervical swelling.
Plunging ranula
How do you treat a ranula?
Remove the feeding sub-lingual gland or marsupialize
What is the difference between a mucocele and a salivary duct cyst?
Mucocele: granulation tissue lining, usually stemming from ruptured duct.
Salivary duct cyst: epithelial lining, developmental origin.
Epithelial lined cavity in oral mucosa.
May be caused by an obstruction in a duct.
Salivary Duct Cyst
Major gland most often obstructed by sialoliths.
Submandibular
Histology:
Intraductal calcified mass with concentric laminations.
Sialolithiasis
Inflammation of the salivary glands.
Sialadenitis
Species most often involved in Acute Bacterial Sialadenitis
Staph. aureus
Non-infectious causes of sialadenitis
- Sjogren syndrome
- sarcoidosis
- radiation therapy
- various allergens
Cheilitis glandularis is most common in whom, and at what location?
- Middle aged and older men
- Minor salivary glands of lower lip mucosa
Treatment for persistent Cheilitis Glandularis with actinic damage
Vermillionectomy
Causes of Sialorrhea
- local irritation (new dentures, aphthous ulcer…)
- Gastroesophageal Reflux Disease
- Heavy Metal and Rabies
- Medications like Lithium and Cholinergic Agonists
