1. Some basics of breast anatomy/histology, with broccoli, for those starting out.

Thanks to Mrs. @Teclis82 for donating part of dinner (reluctantly) for science.

1. #Breastpath Hey all, myofibroblastomas are really sweet. Let’s learn about them. @ADamronMD @TheKarenPinto @KRoSlideReview @Chucktowndoc @jennpincus @LizaMQuintana @drkennethtang @dr_MPrieto 2. Clinical: Uncommon tumors. Well circumscribed, may slowly enlarge over time. Size usu. up to 4cm. Historically (and on boards/RISE exams presently)more common in men, but now seem to occur equally in men and women.
