Most phyllodes tumors have a benign nature, with a high rate of postsurgical recurrence. [2] Rare cases of phyllodes tumors in men are often associated with gynecomastia, suggesting a role for hormonal imbalance.

Presence of periductal stromal condensation and narrow elongated clefted ducts should raise suspicion of a phyllodes tumour.

It is characterized by proliferation of atypical spindle cells surrounding benign mammary ducts and infiltrating adjacent adipose tissue. On physical examination, her right breast was grossly plumper than the opposite, with an approximately 8-cm palpable mass, which was painless and mobile. A retrospective search of our Pathology database from 2000 to 2021 identified 6 PST, all evaluated according to the Armed Forces Institute of Pathology (AFIP) criteria. Malignant phyllode tumors show a combination of marked nuclear pleomorphism of stromal cells, stromal overgrowth defined as the absence of epithelial elements in one low-power microscopic field containing only stroma, increased mitoses (greater than or equal to 10 per 10 HPF), increased stromal cellularity, which is usually diffuse, and infiltrative borders.

The key imaging characteristics were the following: (1) multiple solid lobulated lesions comprising nearly the entire right breast; (2) hypoechoic and heterogeneous echo patterns with internal separations and abundant blood flow were noted; (3) FFDM and DBT showed multiple irregular high-density masses with lobulated margin, partially integrated. Remarkable subcutaneous varicose veins were shown in her right breast.

The PDST has been suggested as part of the spectrum of phyllodes tumor, and the name PDST was adopted in the fourth edition of WHO Classification of Tumors of the Breast published in the year 2012 (12, 13), as these two types exhibit similar pathological features and progression from PDST to phyllodes tumor has been documented (6). In this case, the suspicious feature of multiple internal septa and irregular boundaries were more clearly depicted in DBT than FFDM (Figures35), providing more evidence for a precise diagnosis.
