So let's take a deeper dive to the taxonomy of primary

0:03

bone tumors.

0:04

So when we think about bone tumors, it's

0:07

important to understand exactly what

0:10

the taxonomy is.

0:13

Some of these are discussed particular adapts

0:16

and other modules.

0:19

That you can reference but we're going to sort of do a little bit of a cursory

0:22

overview. So you understand where things fit as we

0:25

proceed with working a patient up for the

0:28

appropriateness for a bone biopsy.

0:31

There's benign.

0:32

Chondrogenic type bone tumors, of

0:35

course in this category, there's chondroblastomas and

0:38

chondromas and the osteochondromas of the world

0:41

and then there are the malignant varieties. Where the chondrosox

0:45

need to be thought about

0:46

and then there are the osteogenic varieties in

0:49

this category. There are also both benign.

0:52

And malignant when we think about benign, there's

0:55

the osteoid osteomus.

0:57

There's the osteoblastomas in the osteomers and then

1:00

of the malignant category, there's the osteosarcomas.

1:03

When we think about fibrogenic tumors similarly, one of

1:06

those key fibrogenic benign, tumors are

1:09

the desmoplastic fibromas and then there's the fibrosox

1:12

in the malignant category.

1:15

Then finally we have the vascular tumors mangiomas of

1:18

the spine being sort of the more benign classic

1:21

lesions, but then there's the managers sarcomas which

1:24

are of course malignant.

1:26

Similarly, we have tumors that are osteoclastic in

1:30

nature that break down bone and that are giant cell

1:33

Rich and these benign tumors are ones

1:36

like the aneurysmal bone cysts the non-assifying from

1:39

Roma's and then the giant cell tumors of the

1:42

bone.

1:43

And then we have the malignant giant cell Platformers of the bone, which is

1:46

an example of the malignant variety. Then we have the notol tumors.

1:49

Of course many of us

1:52

call to mind the benign ones the conventional cordomas,

1:55

but then there are the malignant chordomas

1:58

that we can find the clivus or in

2:01

the sacrum. For example

2:03

The hematopoietic tumors or the benign tumors, we think

2:06

about eosinophilic granulomas in sort of the benign

2:09

langerhans history cytosis conditions, and then

2:12

we think about the malignant tumors lymphomas of

2:15

the world and of course multiple myeloma.

2:18

When we think about other tumors that are seen not

2:21

really nicely fit into any particular category. We think

2:24

about lipomas which of course are no touch

2:27

lesions and then simple bone says and

2:30

then we think about the malignant tumors the LimeWire sarcomas

2:33

and The Plea Market sarcomas of the world.
