Presentation
Discharge from a single duct of the breast. Diagnostic workup.
Patient Data
Age: Adult
Gender: Female
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Ultrasound confirms the solid hypoechoic lesion seen inside the duct. The duct is running superiorly to the left toward the nipple.
Case Discussion
In some cases of intraductal papilloma you can actually see the duct if you look carefully enough. This confirms the location if seen.
