I follow up with Breast Surgeon tomorrow so will get answers,but was wondering if any of you can tell me if I am reading this as it showed Her2 positive as well ad are doing FISH test to confirm. My biopsy showed ER PR strongly positive like the pathology but Her2 neg, and a little difference in Stage, but curious about Her2 positive in pathology. And the of course if it is, what that means for treatment.

Comment
This case was reviewed in consultation by Dr. Flynn. The tumor cells
are positive for AE1/AE3 and GATA3. E-cadherin and P120 staining
supports a ductal diagnosis. HER2 FISH will be ordered. When testing is
complete, the results will be issued in a separate addendum.

Supplemental tumor markers of malignant breast lesions. Testing was
performed on block B3. All immunohistochemical controls show
appropriate staining.

Gross
A. Received fresh for frozen section, labeled "left sentinel node #1"
are multiple portions of yellow, lobulated adipose tissue aggregating to
3.5 x 2.0 x 1.0 cm. Palpation reveals one lymph node candidate (1.7 x
1.0 x 0.6 cm). The lymph node candidate is bisected and submitted
entirely in cassettes A1 and A2. The frozen section was performed at
Sparrow Main by Dr. Pejchal and reported to Dr. Bumpers. Critical
readback of the frozen section diagnosis was read back to Dr. Pejchal by
Dr. Bumpers. Specimen was received on 07/27/2022 at 5:00 p.m. and
reported at 5:20 p.m. HLC/CBR/sal 07/28/2022
B. NOTE: The specimen is excised on 7/27/2022 at 1708 and placed in
formalin on the same date at 1725. The cold ischemic time is
approximately 17 minutes and the total fixation time is approximately 25
hours. The cold ischemic time and fixation times for this specimen are
in compliance with CAP/ASCO guidelines. Received in formalin labeled
"left breast, stitch on axillary tail" is a 398 gram oriented mastectomy
specimen (16.1 cm from medial to lateral, 12.5 cm from superior to
inferior, 3.5 cm from anterior to posterior) with attached skin (10.3 cm
by 7.3 cm) and everted nipple (1.0 x 0.9 x 0.3 cm). There is a single
black suture present designating the axillary tail per the clinician.
The skin is lightly pigmented, wrinkled, and previously dyed blue. The
specimen is inked blue for superior-anterior, yellow for
inferior-anterior and black for posterior. The specimen is serially
sectioned from medial to lateral to reveal three masses and two abnormal
rubbery areas. A 0.7 x 0.4 x 0.4 cm biopsy site filled with blue
gelatinous material is located at the junction of the upper inner
quadrant and lower inner quadrant. Mass one (0.7 x 0.5 x 0.5 cm) is
white, firm, has stellate borders, and is located adjacent to the
aforementioned, possibly-involved biopsy site. Mass one measures 3.3 cm
from the closest skin, 3.3 cm to the closest anterior superior margin,
3.6 cm to the closest anterior inferior margin, and 4.6 cm to the
closest posterior deep margin. In the same plane, 3.0 cm away from the
mass, is an abnormal gray, rubbery area of tissue (0.7 x 0.5 x 0.5 cm)
that is located in the upper inner quadrant. There is a focal area of
rubbery, well-circumscribed tissue (0.6 x 0.5 x 0.4 cm) within a densely
blue-dyed area at the junction between the lower inner quadrant and the
lower outer quadrant. Mass two (2.0 x 0.6 x 0.5 cm) is densely
calcified and located at the junction of the lower inner quadrant and
the lower outer quadrant. Mass two measures 1.0 cm to the closest
anterior inferior margin. Mass three (0.7 x 0.5 x 0.4 cm) is tan, firm,
has stellate borders, and is identified at the junction of the upper
outer quadrant and the lower outer quadrant. Mass three measures 2.6 cm
from the closest posterior deep margin, 5.1 cm from the closest anterior
inferior margin, 4.0 cm from the closest anterior superior margin, and
6.2 cm from the closest skin. The remaining breast tissue is comprised
of approximately 5-10% of white-gray fibrous stroma and predominately
yellow, glistening cut surfaces. Additionally in the container is a 4.0
x 2.3 x 1.0 cm unoriented, fibrofatty tissue fragment. Representative
sections are submitted as follows: B1 and B2 - nipple and underlying
breast tissue, bisected; B3 through B4 - biopsy marker site and adjacent
mass one, with the closest skin and posterior deep margins in B4; B5 -
laterally adjacent tissue to mass one; B6 - abnormal rubbery gray area
close to the mass, with the closest anterior superior margin, bisected;
B7 - rubbery, well-circumscribed area of tissue from the junction of the
lower inner quadrant and lower outer quadrant; B8 and B9 - mass two with
the anterior inferior margin, following decalcification; B10 -
intervening tissue between mass one and two; B11 and B12 - mass three,
with the closest posterior margin in B11 and the closest inferior
anterior margin in B12; B13 and B14 - representative upper inner
quadrant; B15 and B16 - representative lower inner quadrant; B17 and B18
- representative upper outer quadrant; B19 through B20 - representative
upper outer quadrant. HLC/CBR/sal 07/28/2022
