Case Discussion

Left wide local excision: 13 mm, grade 3 invasive carcinoma NST. No lymphovascular or perineural invasion. Clear of margins. Negative single sentinel lymph node. Note marked hypoechoic ultrasound appearance with posterior acoustic enhancement. This should not be confused with a cyst. It often reflects the high grade/cellular nature of the high grade carcinoma.
