The next type of mastitis that I want to
0:03
talk about is granulomatous mastitis,
0:06
and this is an inflammatory breast disease
0:08
which is thought to be associated with
0:09
pregnancy and lactation, but it can occur
0:13
after pregnancy and lactation have ended,
0:16
so often occurs within five years of pregnancy.
0:19
The cause is unknown.
0:21
But there's formation of non-caseating
0:22
granulomas, which are centered on the lobules,
0:26
and there are multiple areas of peripheral
0:29
involvement, and it can have abscesses as well.
0:32
This is more of a chronic process, lasting
0:36
months, presenting as a painful, palpable
0:39
mass, maybe with an area of skin redness.
0:44
And the patient may have systemic symptoms
0:46
of fever and malaise, but the presentation
0:49
is a little bit different than that acute
0:51
lactational mastitis that we saw earlier.
0:56
On ultrasound, we'll see hypoechoic masses
0:59
with tubular extensions into the tissue.
1:01
Mammography may show an
1:03
asymmetry or an irregular mass.
1:05
These cases are often treated with oral
1:07
steroids, um, followed by immunosuppressant
1:10
therapy or prolactin inhibitors.
1:13
They may need, uh, abscess
1:15
drainage or a surgical excision.
1:17
And there's a subtype of this called, uh, cystic
1:21
neutrophilic granulomatous mastitis,
1:24
which is associated with Corynebacterium infection.
1:27
So treatment of the infection can
1:29
help, uh, relieve the symptoms.
