So another case of diffuse cystic lung disease,

0:03

but this is weird, right?

0:05

Look at these. So you get these weird bizarre shaped cysts,

0:08

some with thick walls, some with thin walls.

0:11

You see small Cheerios like nodules as well, as well

0:14

as other small central modular nodules.

0:18

So we scroll through, we see more of this weirdness going on

0:22

and these central lobular nodules

0:24

with some Cheerios like nodules as well.

0:27

And then the bizarre shape cysts are

0:28

so just all over the place.

0:30

And so as we get down to

0:32

where the disease is a little bit less severe, we start

0:33

to see more of these central lobular nodules

0:35

and cheerios like nodules.

0:37

And so the lung bases are nearly completely spirited,

0:40

especially in a schizophrenic angles.

0:42

This is classic long han cell histiocytosis,

0:45

which again is smoke related lung disease associated

0:47

with pulmonary hypertension as well,

0:48

which this patient looks like they have.

0:49

Pulmonary artery is dilated.

0:51

So beautiful example of long han cell histiocytosis

0:55

and they all sort of look like this, right?

0:57

Uh, you can get LCH in women as well as a woman,

1:00

but especially in a man.

1:02

In a man. If you see diffuse cystic lung disease,

1:06

the first thing you think about it is LCH

1:08

and characteristically.

1:09

They have this sort of ugly pattern.

1:11

It's like not aesthetic pattern.

1:12

And so that points to pulmonary lung cell histiocytosis

1:17

as the cause for this disease pattern.
