Q

What are RFs for SCC?

A

High grade recur in 25-30% with 5 year survival of 50%

45
Q

What are mucoepidermoid carcinomas composed of?

A

Mix of sq. cells, mucus secreting cells, intm cells

46
Q

What is the MC malignant tumor of minor salivary glands?

A

Adenoid cystic carcinoma

47
Q

What salivary gland tumor is slow growing and may neurally invade?

A

Adenoid cystic carcinoma

48
Q

What is the prognosis for an adenoid cystic carcinoma?

A

Despite resection, 50% disseminate to lungs, bone, liver, and brain often decades after removal. 5 year survival 60-70%, 10 year 30%, 15 year 15%

49
Q

What is the MC benign salivary gland tumors?

A

MC- Pleomorphic adenoma, usually parotid

2nd MC- Warthin tumor (almost always parotid)

50
Q

What is hte MC malignant salivary gland tumor?

A

Mucoepidermoid carcinoma

51
Q

What is the MC malignant salivary gland tumor of minor salivary glands?

A

Adenoid cystic carcinoma

52
Q

Which salivary gland is most often involved in salivary gland neoplasms?

A

?

53
Q

What is esophageal atresia and TEE?

A

Congenital defect where the esophagus does not develop properly.

Most cases the upper esophagus ends (atresia) and does not connect with the lower esophagus and stomach.

The top end of the lower esophagus connects to the windpipe (this type is called a tracheoesophageal fistula TEF).

Occurs in 1/3000 live births.

54
Q

What is esophageal stenosis?

A

NARROWING of esophagus d/t injury and inflammation from chronic gastroesophageal reflux, irradiation, or caustic injury.

It may also be congenital. Seen in 1/50,000 births.

55
Q

What is the difference between esophageal mucosal webs and Schatzki rings?

A

Esophageal mucosal webs:

  1. Protrusions of MUCOSA that cause obstruction
  2. UPPER esophagus

Schatzki Rings:

  1. Like webs but THICKER and CIRCUMFERENTIAL
  2. may contain muscularis propria
  3. LOWER esophagus
56
Q

What is plummer vinson syndrome?

A

upper esophageal webs assoc. w/ chronic iron-deficiency anemia, glossitis, oral leukoplakia, and spoon nails

57
Q

Zenker’s diverticulum

A

Above the upper esophageal sphincter as an outpouching of mucosa and submucosa through a weakened posterior cricopharyngeus muscle

A

Separation of diaphragmatic crura and protrusion of the stomach into the thorax through the defect

Can be congenital but most are acquired (50% >50 yrs old have hiatal hernia)

Sx range: similar to GERD, ulceration, stricture, and hematemesis

60
Q

What is the MC type of hiatal hernia?

A

95% of hiatal hernias are the sliding type (Type 1)

  3. cytomegalovirus (CMV) esophagitis
62
Q

What is the suspected pathogenic mechanism of eosinophilic esophagitis?

A

Thought to be some type of allergic reaction to food allergens but underlying pathogenesis not completely understood

Many pts have other allergies such as allergic rhinitis, atopic dermatitis, or asthma

63
Q

What is the microscopic appearance of eosinophilic esophagitis?

A

Bx shows ↑ eosinophilic inflam. w/ basal epithelial hyperplasia w/ absence of acute inflam.

64
Q

What is the clinical presentation of eosinophilic esophagitis and how does it differ in adults and children?

A

Sx of adults and teens:
Food impaction
Persistent dysphagia
GERD Sx that fail to respond to medical intervention

Sx of children:
Feeding disorders, 
vomiting, 
abdominal pain, 
dysphagia, and 
food impaction
65
Q

What is Barrett’s esophagus?

A

Characterized by conversion of normal esophageal squamous mucosa → metaplastic columnar epithelium

Results from chronic GERD (seen in 10% of pts w/ symptomatic GERD)

66
Q

How do you diagnose Barrett’s esophagus?

A

BOTH endoscopic & histologic evidence of metaplastic columnar epithelium

67
Q

What is the major complication of Barrett’s esophagus?

A

↑risk of esophageal glandular dysplasia & adenocarcinoma (rare complication)

68
Q

What are the RF for esophageal adenocarcinoma?

A

Pt’s w/ glandular dysplasia

95% of cases arise from Barrett’s esophagus and long-standing GERD

69
Q

What are the RFs for esophageal squamous cell carcinoma?

A

o Alcohol or tobacco use
o Caustic esophageal injury
o Achalasia
o Tylosis (genetic disorder characterized by thickening (hyperkeratosis) of the palms and soles)
o Plummer-Vinson syndrome
o Frequent consumption of very hot beverages
o HPV infection (very rare)

70
Q

What is the MCC of esophageal squamous papillomas?

A

HPV

71
