Nelson P, G, L Path Objectives Flashcards
Pancreatic: agenesis divisum annular ectopic
agenesis: does not form
divisum: dorsal and ventral pancreatic ducts don’t fuse -> usually benign, chronic pancreatitis possible
annular: ring-like band of pancreatic tissue encircling duodenum -> obstruction
ectopic: often in Meckel’s diverticulum
Chronic pancreatitis may lead to
exocrine pancreatic insufficiency
Type I autoimmune pancreatitis associated with
IgG4-related disease
IgG4-related disease path
fibroinflammatory condition characterized by tumefactive lesions, lymphoplasmacytic infiltrate, IgG4-positive plasma cells
Pancreatic pseudocyst causes
acute pancreatitis
trauma
Serous cystoadenoma
Mucinous cystic adenoma/adenocarcinoma
intraductal papillary mucinous neoplasm
Serous cystoadenoma: small w/ clear serous
Mucinous cystic adenoma/adenocarcinoma: large, mucin filled–benign of malignant
intraductal papillary mucinous neoplasm: benign or malignant, arises from ducts
Pancreatic cancer is # what killer in US due to cancer
4
Pancreatic carcinoma most common type
pancreatic exocrine carcinoma
ductal cell
spreads quickly –> frequently unresectable
Whipple procedure
resect head of pancreas, pylorus, and duodenum
attach pancreas to blind end of bowel
attach bile duct to bowel
distally attach stomach to slit in bowel
Phryian cap of gallbladder
normal anatomical variant
confused w/ stones
Stone types
cholesterol: fat fertile females over forty
pigment: chronic hemolysis
Choledocholilithiasis
hardening of galbaldder
Chronic cholecystitis etiology
super-concentrated bile or repeat acute
Porcelain gallbladder
2˚ to chronic cholecytisits
Adenomyoma of gallbaldder
intramural thickening, not true neoplasm
