Lymph drainage from the vulva and the foot as demonstrated by 198Au.

Abstract

From the central part of the labium majus the lymphatic transport of 198Au is invariably bilateral to inguinal and pelvic lymph nodes. Thus, bilateral inguinal and low pelvic lymph-adenectomy is logical in the treatment of carcinoma of the vulva. 198Au injected subcutaneously and Lipiodol injected intralymphatically in the dorsum of the foot were transported exclusively to ipsilateral inguinal and pelvic lymph nodes. Thus, there is no need for contralateral lymphadenectomy in malignancies on the dorsum of the foot.
