The lesion in the subareolar left breast is an infiltrating ductal carcinoma histologically confirmed on ultrasound guided needle biopsy.
This patient had a normal mammogram three years ago. The innumerable small mass lesions are intramammary foci of metastatic breast carcinoma from the primary lesion in the left breast.
This is a very unusual finding in breast imaging. The patient did not have enlarged lymph nodes on mammography or ultrasound.
