title: Microdochectomy assisted by ultrasound-guided indigo carmine staining of intraductal lesions: a case report.
abstract: Spontaneous bloody nipple discharge from a single duct is a significant clinical problem. When performing preoperative marking of the discharging duct, it is sometimes difficult to identify the duct owing to intermittent discharge. Precise preoperative marking of the discharging duct and intraductal lesions is very important to avoid unnecessary wide excision of breast tissue or failure to remove the cause of nipple discharge. We herein present a case of preoperative ultrasound-guided indigo carmine staining in a patient with no discharge on the day of surgery. When a dilated duct is visualized on ultrasound, the targeted duct can be localized using indigo carmine staining, and it is possible to perform a precise minimal volume microdochectomy.
