Successful Mapping of Lymphorrhea Using Patent Blue Dye after Lymph Node Dissection for Malignant Melanoma

Patent blue is a dye that has been used for intraoperative lymphatic mapping. We used this mapping method on a patient with lymphorrhea after groin dissection. We easily detected the lymphatic channel causing lymphorrhea and successfully ligated it. This technique may have great merit for treating of lymphorrhea.
