1

possible complication of acute pancreatitis

abscess formation

2

gross appearance of acute pancreatitis

loss of the normal lobular surface markings

3

gross appearance of chronic pancreatitis

shrunken and fibrotic. The main duct is dilated and filled with calcified secretions

4

complications of acute pancreatitis

pseudocyst- NO EPITHELIAL LINING
Infected necrosis (lethal)

5

Benign tumors of the exocrine pancreas include

pseudopapillary tumor, serous cystadenoma and mucinous cystadenoma

6

Solid pseudopapillary tumors
gross:

round, well-demarcated, with solid and cystic areas, often with hemorrhage noted on cut sections

7

the most frequent cystic tumors of the pancreas (50% of all cystic tumors)

Mucinous cystadenomas

8

Mucinous cystadenomas are usu benign but may transform into

a malignant tumor

9

second most common cystic tumor of the pancreas

Serous cystadenoma

10

serous cystadenoma
gross:
histo:

honeycombed appearance on pathology is also characteristically seen on the CT scan

a bx reveals small cysts which are lined by ciliated cuboidal epithelium

11

serous cystadenoma is known to be associated with

Von Hippel-Lindau syndrome

a genetic condition in which cysts often develop in the pancreas, liver and kidney and hemangioblastomas are found in different organs including the cerebellum, spinal cord, kidney and retina as well as cafe o’lay spots

12

The most common type of pancreatic cancer
(90 - 95% of all malignant pancreatic tumors) _______

pancreatic adenocarcinoma
generally has a very poor prognosis

13

stones are formed in the gallbladder but may pass distally into other parts of the biliary tract

cholelithiasis

14

if gallstones migrate into the ducts of the biliary tract, the condition is referred to as

choledocholithiasis

15

the presence of stones in the gallbladder (cholelithiasis) can lead to an inflammatory condition called

cholecystitis

16

Infectious agents that cause cholecystitis include

E. coli, Klebsiella, Pseudomonas, B. fragilis and Enterococcus

17

gallstone can be divided into 3 types

cholesterol stones
pigment stones
mixed stones

18

to be classified as cholesterol stones they must be at least

80% cholesterol by weight

19

what percent of cholesterol stones are radiolucent on XRAY's?

10%
the other 90% will be negative for cholelithiasis

20

mixed gallstone typically contain __-__% cholesterol

20-80%

21

pigment gallstones contain the least cholesterol, with less than ______% cholesterol

20%

22

_________ is characterized by abnormal deposition of cholesterol and triglyceride fill macrophages in the lamina propria of the gallbladder

cholesterolosis

23

foci of cholesterol filled macrophages. Diffuse involvement of the mucosa such as in this specimen is referred to as a "strawberry gallbladder".

cholesterolosis

24

Rokitansky-Aschoff sinuses are seen in the muscularis for which condition?

chronic cholecystitis

25

a calcification of the gallbladder believed to be brought on by persistent inflammation due to the presence of gallstones is the pathphysiology for which condition?

porcelain gall bladder

26

the term used to describe a gall stone that has passed into the common bile duct

choledocholithiasis

27

concentric (onion skin–like) peri-ductal fibrosis is seen in what two conditions?

ascending cholangitis (secondary sclerosing cholangitis)
primary sclerosing cholangitis

28

The majority of all carcinomas of the gallbladder are found to be well differentiated

adenocarcinomas

29

adenocarcinoma of the gall bladder shows what types of cells?

intestinal type
