Q

T/F: Frothy saliva is a sign of xerostomia.

A

True

17
Q

Which lesion can be characterized by “blossoms on a tree” look in a radiograph?

A

BLEL

18
Q

In which disorder do you see remnants of ductal epithelium in the form of epimyoepithelial islands?

A

BLEL

19
Q

T/F: Sjögren syndrome is sometimes thought of as a continuation of BLEL.

A

True

20
Q

What is the difference between primary and secondary Sjögren syndrome?

A

Primary (sicca) - xerostomia and keratoconjunctivitis

Secondary - sicca plus another autoimmune disease

21
Q

T/F: Sjögren syndrome has a male predilection.

A

False

More common in females

22
Q

T/F: Serology is a specific test for Sjögren syndrome.

A

False

Is often used as diagnostic tool but is non-specific

23
Q

Which antibodies can help diagnose Sjögren syndrome?

A

Elevated IgG, rheumatoid factor, anti-nuclear autoantibodies, anti-SS-A, anti-SS-B

24
Q

What histopathogical features can be used to diagnose Sjögren syndrome?

A

Labial salivary gland biopsy

Looking for aggregates of >50 lymphocytes and plasma cells in a gland

25
Q

T/F: Patients with Sjögren syndrome have a 44x increase in lymphoma.

A

True

26
Q

What is thought to be the cause of Necrotizing sialometaplasia?

A

Due to ischemic necrosis from a variety of causes (traumatic injury, dental injection, ill fitting dentures)

27
Q

A

False

Rare in children

28
Q

What is the most common location for necrotizing sialometaplasia?

A

Hard/soft palate

29
Q

How does necrotizing sialometaplasia typically present?

A

Sharply demarcated ulcer on the palate

Patient may say “piece of my palate fell out”

30
Q

Which salivary gland disorder can be easily mistaken for SCC histopathologically?

A

Necrotizing sialometaplasia

31
Q

Pseudoepitheliomatous hyperplasia (PEH) of surface epithelium is a characteristic of which salivary gland disorder?

A

Necrotizing sialometaplasia
