Just a few words more about Pleomorphic adenomas.
0:05
As you can see, the majority of Pleomorphic adenomas,
0:08
we usually say about 80%, occur in the parotid gland.
0:12
Of all the pleomorphic adenomas,
0:14
about 8% occur in the submandibular gland,
0:18
about six and a half percent in the minor salivary gland.
0:21
And we just saw one of those in the hard palate, and then a
0:25
smaller proportion in the sublingual gland. In the
0:28
parotid gland, most are in the superficial lobe.
0:31
They may occur in about 1% to 5%,
0:34
and they may be multicentric in about 0.5%.
0:39
Now, the thing about Pleomorphic adenomas is that it should
0:42
be taken out in its entirety with its capsule.
0:47
If that capsule is violated at the time of surgery,
0:50
there is the possibility of seeding of the operative
0:54
bed with pleomorphic adenoma tissue.
0:58
That becomes a disaster because you got lots of little
1:00
pleomorphic adenomas that start growing along those seeds.
1:04
And it's very difficult to eradicate the tumor completely
1:09
once that has occurred. As I said,
1:12
because of the risk of carcinoma ex pleomorphic adenoma,
1:16
a malignant degeneration, if you will,
1:18
of pleomorphic adenomas.
1:20
These are treated aggressively with surgery.
1:24
Rather than being left in the parotid gland
1:27
as a benign tumor,
1:28
they want to take these out because they worry about,
1:31
over the course of time, malignant degeneration.
1:34
Now, if you wait 20-25 years,
1:37
that rate of malignant degeneration gets as high as 20%.
1:42
Usually we don't see that.
1:43
We see them being discovered, taken out,
1:46
and being cured of the disease.
1:51
But that is the risk of Pleomorphic adenomas.
1:55
So what I'd like to do now is to show you a few more cases
1:58
of different appearances of Pleomorphic adenomas.
