Mucocele
Ranula
Sialothiasis
Necrotizing Sialometaplasia
2
Q
Infectious Salivary gland lesions 2

Viral sialadenitis (mumps)
3

Auto immune salivary gland lesions 2
A
Sarcoidosis
Sjorgens syndrome
4
Q
Mucocele
Occurence
Results from
Age
Location
Hx
App
A
- Aka salivary retention phenomenon
- One of the most common soft tissue enlargements
- Results from rupture of a salivary gland dust and spillage of mucin
- Often to trauma
- More in children
- 80% lower lip
- Hx of recurrent swelling that may periodically rupture
-
App
- Dome swelling, bluish-translucent
5
Q
Mucocele Tx
A
- Some heal themselves
- Chronic require surgical excision
- Adjacent minor glands must be removed
- Tissue must be tested for tumor
- Excellent prognosis
6
Q
Ranula
Usually due to which gland
Location
Age
App
Tx
A
- Mucoceles that form on floor of mouth
- Usually sublingual gland( also SM & Minor)
- Sublingual- body of gland or along superficial ducts of Rivini
- Children
- App
- Blue, dome shaped
- Usually lateral to midline
- larger than mucocele
- Tx
- excision
7
Q
Sialolithiasis
Definition
Promoted by
Gland
App
Pain during
A
- Sialolith: calcified structure w/i salivary ductal system
- Deposition of calcium salts around a nidus of debri within lumen
- Can be promoted by chronic sialadenitis and partial obstruction
- Not related to systemic derrangement in ca metabolism
- Submandibular gland/duct (Ony major)
- Whartons duct
- If palpable firm
- Pain and swelling during times of salvation (mealtime)
8
Q
Bacterial sialodenitis
What is it
Result of
Allows
Causes
Gland
Dist
Symptoms
A
- Inflammation of salivary glands (acute or chronic)
- Result of ductal obstruction or decrease in saliva flow
- Allows retrograde spread of bacteria
- Blockage: Sialolith, congenital structure, adjacent tumor
- Dec flow: dehydration, debilitation, meds
- Usually parotid
- May be bilateral
- Acute pain, swelling lymphadenopathy
- Sometimes fever, malaise, leukocytosis
9
Q
Viral Sialadenitis (Mumps)
Cause
Symptoms
Galnd
dist
A
- Paramyxovirus Rubulavirus
- low fever, headache, malaise, anorexia, myalgia
- Swelling of salivary glands
- Parotid most freq
- most bilateral
- Swelling from ear to ear
- diagnose from clinical presentaton
10
Q
Necrotizing sialometaplasia
Def
Due to..leading to
Resembles
Location
App
Tx
A
- Locally destructive inflammatory condition
- Prob due to ischemia leading to infarction of salivary glands leading to
- Squamous metaplasia & hyperplasia of epithelium
- Resembles SCC
- Mimics a malignant process, both clinically and micro
- Most on post palate
-
App
- App non-ulcerated swelling
- After 2-3 wks craterlike ulcer
- Resolves in 5-6 wks
- Always biopsy
- No tx needed
11
Q
Sarcoidosis
Def
Cause
Formation of
Common pop
App
A
- Multisystem, granulomatous disorder of unknown cause
- Improper degradation of antigenic material
- Formation of noncaseating granulomatous inflammation
- More common in AA
- App
- include masses, ulcerations on lips
- May have occular involvement
- Like Sjorgen
- Diagnosis on clinical, radio, histo
- Inc antiotensin-converting enzyme
- Most resolve in 2 yrs naturally
12
Q
Sjorgen Syndrome
Cause
2 forms
A
- Auto-immune disorder
- Antibodies to salivary glands and other exocrine glands
- Intial inflammation with progression to destruction of salivary glands
- Primary SS:Xerostomia and xerophthalmia
- Secondary SS: sicca syndrome + autoimmune disease (rheumatoid arthritis and lupus)
13
Q
Sjorgen Syndrome
Gender
App
Test
Lab abnormaliies
Tx
Risk of
A
- Females
- App
- principal lesion of xerostomia
- Tongue often becomes fissured, atrophy of filiform
- Schrimmer test for tear secretion
- Lab abnormalities
- Antinuclea antibodies in blood
- Rheumatoid factor
- Inc erythrocyte sedimentation rate
- Tx
- Supportive, articial tears, saliva
- Inc risk caries
- 40X risk of developing lymphomas
14
Q
Sialodenosis
Desc
Assoc with
Cause
Dist gland
A
- Non-inflammatory disorder characterized by SG enlargement
- Assoc with underlying systemic problems
- Diabetes, malnutrition, alcholism, bullimia
- Deregulate innervation of glands, causing granule accumulation
- Bilateral parotid swelling, pain
- SubMand sometimes, may have xerostomia
- Next runner up after sjorgens
15
Q
Sialorrhea
A
- Excessive salvation, various causes
- Aphthous ulcers, ill-fitting dentures, GERD, heavy metal poisoning
- Meds for alzhimers & myasthenia gravis
- Neurological disorders may drool but have norm saliva
