Case 58 Answer
This is a mixed solid and cystic mass, with documented arterial flow in the solid portions, and is highly suggestive of malignancy. If you called it BI-RADS 4, you still pass.
If there had been a history of trauma or infection, and if there had been no blood flow within the solid portions, one could consider abscess or hematoma, and performing a follow-up ultrasound after treatment would be reasonable.
Biopsy showed Squamous Cell Carcinoma. This is a very rare tumor to occur in the breast. Other rare tumors in the breast include adenoid cystic carcinoma, granular cell tumors, and sarcomas such as angiosarcomas.
This patient returned 3 months after surgery with a lump underneath her incision. An ultrasound was performed.
What is your impression?
