We are excited to share the first case in our #breastimaging and #breastpath correlation series! This case highlights challenges of imaging/management and the pathologic diagnosis.
56 yo woman with left breast focal asymmetry and calcifications. Screening mammogram. @DrJordanaP
Diagnostic mammogram and ultrasound were performed. A presumed ultrasound correlate was found with calcs and vascularity. What is the next step? What BI-RADS would give? @DrJordanaP
Ultrasound-guided core needle biopsy was performed. Specimen radiograph done -- no calcs seen. Post-biopsy mammo shows clip near target. @DrJordanaP
Great discussion everyone! This is a low-grade atypical proliferation (monotonous small nuclei). Based on how focal (quantity) and that it does not completely involve the spaces (quality) this is best cat as ADH (micropap and some rigid bridges) and FEA. Some CCC in background.
The distortion and periductal fibrosis raised the possibility of an associated sclerosing lesion (added in a note). Rare tiny calcs were seen (below) but were not detected in specimen radiograph, so additional levels wouldn't be helpful for calcs.
So... is this concordant? What should next steps be? #breastimaging
From @DrJordanaP : Concerned about the initial finding - new focal asymm with calcs. ADH felt discordant, esp bc not sure how great our sample was (no calcs in specimen mg). So we did stereo and targeted calcs. Post-mg shows new bar clip near coil clip.
Path from biopsy #2 continued. Thoughts? Do we have the target? Summary teaching/take-home points to follow!
Thank you all for following along! Biopsy #2 showed spectrum of atypia -- FEA, through ADH, to areas with sufficient cyto and arch atypia for low-grade DCIS. There was periductal and stromal fibrosis associated with the atypia (same on excision) -- the asymmetry seen on imaging.
#breastradpath correlation for biopsy #2: concordant.
Here are our take home points for case #1! @DrJordanaP
2/ The biomarkers provide predictive information (how a patient may respond to targeted therapy) as well as prognostic information. It helps to organize patients into treatment groups that follow different algorithms and guidelines.
3/ Biomarkers are evaluated in routine clinical mgmt of patients with breast cancer. The 3 routinely tested:
Hormone receptors (HR): Estrogen receptor (ER) and Progesterone receptor (PR)
&
Human epidermal growth factor receptor 2 (HER2)
44 yo woman. On req: "faint grouped microcalcs." #breastimagers separate calcs and no calcs cores into separate containers (so helpful!). There was only one block of cores with calcs. Here are the #breastpath images. Thoughts? Next steps?
You are all thinking the way I did! For cases with calcs, I always review the imaging, and in particular the specimen radiograph, to see the morphology of the calcs I should look for. Check out the imaging from @DrJordanaP 👇
The tiny calc in the initial levels of the CNB are not the same as the calcs seen on imaging. We need to find those calcs --> LEVELS! (I haven't heard it called steps before! I like!) #breastradpath correlation is so important here!
Hi #pathology tweeples! I just realized that the callus I have on my pinky is from using it to steady my hand as I dot 😂(with my green pen of course 😉). I must dot A LOT! 💪🔬
I have some #path (mostly) dotting related questions out of curiosity.
Breast excision. What is your diagnosis? Would you do stains? #breastpath
Thanks everyone! This is LCIS involving collagenous spherulosis. I did IHC. The e-cad was stronger than I expected but showed granular staining so I followed up with p120 and beta-catenin to illustrate the different stains.
