Galactocele in the Axillary Accessory Breast Mimicking Suspicious Solid Mass on Ultrasound

Abstract EN

Galactoceles are the most common benign breast lesions during breastfeeding period that can mimic carcinomas.

We report a galactocele with malignant appearance on ultrasound in the accessory breast.

The patient was a 32-year-old lactating woman presented to our hospital for considerable swelling in the left axilla.

Ultrasound examination revealed a hypoechoic mass with heterogeneous echogenicity and irregular shape and margins.

Sonography-guided aspiration was performed.

Aspiration of milky fluid and resolution of the axillary lump after aspiration confirmed the diagnosis of galactocele.

Galactocele can present as a suspicious tumoral lesion in the axillary accessory breast and diagnostic aspiration can help in correct diagnosis of this rare lesion in the accessory breast.
