Rosai Chapter 13 - Esophagus Flashcards
Esophagus approximately measures:
25 cm
Margin of upper esophageal sphincter
Cricopharyngeal muscle
Vertebral counterpart of the upper esophageal sphincter
C6
Measurement of upper esophageal sphincter from the incisors
15-18 cm
Margin of lower esophageal sphincter
Gastroesophageal junction (GEJ)
Measurement of lower esophageal sphincter from the incisors
40 cm
The point at which the tubular esophagus flares to the saccular stomach
GEJ
GEJ is recognized endoscopically by the:
proximal margin of the gastric folds
This is the irregular meeting point of the squamous and glandular epithelia
Squamocolumnar junction (SCJ)
SCJ is also known as:
“Z line”
SCJ or Z line will be found:
proximally displaced above the GEJ
Most common tracheoesophageal anomaly
Type C
This type of tracheoesophageal anomaly is characterized by esophageal atresia with a fistula between the lower portion of the esophagus and the respiratory tree
Type C
Most common location of heterotopic gastric mucosa
postcricoid region
other name of Heterotopic pancreatic tissue
Pancreatic acinar metaplasia
Most common type of diverticulum in the upper aerodigestive tract
Zenker diverticula
Zenker diverticula is located in the:
upper portion of the esophagus
This esophageal cysts is lined by squamous or columnar epithelium sometimes ciliated
Inclusion cysts
This esophageal cysts is arising from cystic dilation of submucosal glands
Retention cysts or Mucoceles
This esophageal cysts can be of esophageal, bronchial, or gastric origin
Developmental cysts
