Intramammary metastases from breast carcinoma

Case contributed by Garth Kruger
Diagnosis certain

Presentation

Palpable mass in the subareolar left breast.

Patient Data

Age: 67 years
Gender: Female

The lesion in the subareolar left breast is an infiltrating ductal carcinoma histologically confirmed on ultrasound guided needle biopsy.

Case Discussion

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.
