Intraductal papilloma:
Solitary.
00:04
Found within lactiferous
duct or sinus.
00:07
Picture that for
me in your head.
00:09
You’re by the nipple and then
you on to a lactiferous sinus,
this is where you would find it.
00:14
More than 80% will present
with spontaneous,
unilateral,
either serous or bloody
nipple discharge.
00:21
That discharge becomes
really important for you.
00:23
Benign.
00:25
Rarely more than 1
cm in diameter.
00:27
Most solitary intraductal
papillomas are benign,
but if there’s
multiple papillomas,
then you’d find there to be
an increased risk in cancer,
you can use the same concept
earlier that we used for polyps.
00:40
Remember familial
adenomatous polyps?
It doesn’t matter
what kind of polyp,
but if you have hundreds
and thousands of them,
you increase the risk of cancer.
00:48
Here, we have a papilloma,
if you have increased
number of papilloma,
and it’s multiple because
usually it’s solitary.
00:54
Then it is concerning
that breast cancer,
you’re increased in risk for it.
01:01
In intraductal papilloma,
as you would show in the
histologic picture,
is that within the
lactiferous sinus,
you will then find
a tumor itself
and there’ll be dilation
of the duct,
intraductal papilloma by
the lactiferous sinus.
01:16
Now because of how close
the intraductal papilloma
is to the nipple,
and this is why it
becomes important.
01:22
If you start having damage to the
lactiferous sinus and the duct,
of course, right
from the nipple,
you’re going to have discharges.
01:32
Either serous or
bloody, is that clear?
So don’t try to memorize that.
01:36
I mean understand that if
you’re so close to the nipple
and you’re causing damage,
of course, you’re going
to have bloody discharge.
01:42
80%, remember.
