Case contributed by Dr Bruno Di Muzio


Patient with a history of a nodule in the medial quadrant of the left breast that became palpable and hardened, growing in size in a few months.

Patient Data

Age: 65
Gender: Female


Patient has no previous exam accessible. Mammography images identify an area of focal asymmetry located in the medial quadrant of the left breast. ACR BI-RADS 4C.

Clinical examination and mammography findings referred the patient to biopsy of the left breast.


Ultrasound-guided breast core-biopsy

This lesion, given its size and palpability, becomes easy to biopsy, virtually eliminating the ultrasound. The technique used in our service is summarised as: skin antisepsis, local block with 10 mL of 1% lidocaine, a small incision with a scalpel 11 (enough to overcome resistance and allow the entry of the needle-core biopsy), guided introduction of the needle core biopsy with the removal of three or four fragments. The needles commonly employed are of 16 or 14 gauge.

Case Discussion

This case was pathological proven to be an invasive Ductal Carcinoma, a type of breast cancer.

Observation: The breast photo was obtained with patient permission and under the hospital privacy rules.
