We can broadly divide the pancreatic lesions

0:03

into solid and cystic, and solid lesion can

0:07

arise from endocrine cells or exocrine cells.

0:12

And as I said earlier, 95% of the

0:14

cells of the pancreas are exocrine.

0:18

Cystic lesions can be further

0:20

divided into proper cysts,

0:23

those are lined by epithelium, or pseudocyst,

0:27

those are not lined by the epithelium or

0:29

cystic neoplasms from the exocrine cells,

0:33

the most common pathology which arises.

0:36

We encounter in the real life is adenocarcinoma.

0:39

95 percent of the tumors are adenocarcinoma.

0:43

But other uncommon tumors are also possible,

0:45

like acinar cell or squamous cell, but

0:48

those are very uncommon, and we are not

0:49

going to deal with those in our talk here.

0:52

The endocrine tumors are basically neuroendocrine

0:55

tumor or carcinoid, which can be most common

0:58

is insulinoma, most common is insulinoma.

1:03

Or Gastrinoma cyst.

1:06

As I said earlier, these

1:07

are, these are the real cysts.

1:09

They are lined by epithelium, and they

1:10

can be seen with some continental anomalies

1:13

or continental syndrome to be very precise,

1:15

like one hippo limbo or polycystic disease.

1:20

And pseudocyst is basically complication

1:22

of pancreatitis, and the neoplasm, the

1:26

cystic neoplasm can be from the duct or

1:30

from outside the duct, extra ductile.

1:34

So from the duct, which we have

1:35

most commonly seen in real life.

1:37

IPMN and extra ductile are.

1:41

So,

1:48

we will be dealing all with all these

1:50

legions in our presentation today.
