چکیده (انگلیسی):

A 44-year-old woman was referred to our hospital with pathological nipple
discharge from her left breast. Ultrasonography revealed a solid tumor beneath her left areola
that measured 17 mm in diameter with a dilated mammary duct. Contrast-enhanced magnetic
resonance imaging showed an early-enhanced cystic tumor and a dilated mammary duct. We
performed a duct-lobular segmentectomy using near-infrared indocyanine green (ICG)-fluorescence
imaging. Under general anesthesia, a silicone tube was inserted into an orifice of a fluiddischarging
mammary duct, and 1 mL dye-fluorescence liquid containing ICG and indigo
carmine was injected into the mammary duct. A periareolar incision was made, and the fluorescence
image of the demarcated mammary duct segment was obtained. The mammary duct
segment was dissected, along with the demarcation line. The cystic lesion and dilated
mammary duct were fully resected, and the pathological diagnosis was intraductal papilloma
of the breast. We report that near-infrared ICG fluorescence could be applied for imaging of
the mammary duct segment, and the fluorescence image allowed for easier duct-lobular
segmentectomy for nipple discharge.
