Step 1: Trace the superficial lymphatic pathway from the medial foot upward.
Step 2: Lymph from the great toe and the medial foot runs alongside the great saphenous vein. Following this route, it reaches the superficial inguinal nodes in the groin as the first drainage station, confirming that choice.
Step 3: The deeper options are downstream or unrelated. The deep inguinal nodes chiefly handle deep limb lymph and efferents from the superficial set, and the external and internal iliac nodes are pelvic relays that receive from the inguinal groups rather than directly from the toe.
Step 4: The initial nodes draining the great toe skin and fascia are thus the superficial inguinal group.
