Happy Saturday everyone! Let’s discuss Breast Consult Case of the Week 8 #BCCW8. Yet again, I was expecting a modicum of controversy but all of you were right on the mark. The question was actually not whether this was a fibroadenoma or phyllodes tumor, but whether it was a benign or borderline phyllodes. Honestly, despite everyone’s accurate interpretation, I can completely understand the referring pathologist’s diagnostic impression. Here we have a very large fibroepithelial lesion with increased stromal cellularity, an intracanalicular growth pattern but with patent ducts imparting a nascent phyllodes-like pattern, much epithelial proliferation, and a suggestion of subepithelial stromal condensation. So why is it not a phyllodes tumor? In truth, it isn’t because I don’t want to call it that. The one feature that is the most telling in my opinion, other than the patient’s very young age, is the striking uniformity of this mass. All components are distributed evenly, which, to me, is highly unusual in a phyllodes tumor, particularly one this large. Remember that phyllodes tumors are notoriously heterogeneous, which is somewhat counterintuitive when considering hyperplastic vs. neoplastic lesions of the breast, but that’s how this cookie crumbles. The next question is, does it matter? Benign phyllodes and fibroadenomas have very similar biologic behaviors and an excellent prognosis. So why should we waste time and effort trying to distinguish one from the other? Well, in many instances, it really doesn’t, which is why I am in favor of a noncommittal diagnostic category not just for biopsies, but also for excisions. But that’s another discussion. In this particular patient, given the size and the margin status of this lesion (positive), a diagnosis of an incompletely excised phyllodes tumor may lead to an unnecessary simple mastectomy, the physical and psychological consequences of which are inscrutable and unpredictable. A conservative diagnosis is therefore the way to go, when the anticipated outcome is cure. Voilà. One can go on and on with this topic without a convincing resolution, but we keep trying.
