Reports of treatment of varicose veins of the anterior accessory saphenous vein (AASV) alone without greater saphenous varicose veins are limited, and most cases are adults. We here report a rare case of what appears to be congenital AASV varicose veins. Case: A 69-year-old woman. She had a mass in her left knee after birth, but the bulge naturally decreased. When she was 18 years old, she visited the department of plastic surgery at a university hospital. She was offered treatment with myodermal flap, but she did not want to do so and subsequently left it untreated. About 50 years later she visited our department for treatment. The anterior surface of the left knee was depressed, and superficial varicose veins matched the site. Ultrasonography and contrast-enhanced CT scan were performed. No abnormalities in deep veins or arteries were observed, and varicose veins with valvular insufficiency of the left AASV were diagnosed. Endovascular radiofrequency ablation of the left AASV was performed. Foam sclerotherapy with 1% polidocasclerol was added after 1 month. Although the detailed course of childhood is unknown, it is considered to be a rare varicose vein in which the hemangioma from birth partially degenerates and shrinks spontaneously with growth.
