The pathophysiology is not yet well understood. Leukocytoclastic vasculitis is proposed to be the underlying cause resulting in reactive lymphedema. Prolonged standing with full knee extension and minimal movement for a prolonged period of time is postulated to induce a temporary failure in pumping the venous and lymphatic systems in the calf region leading to acute gravity-dependent venous congestion, deposition of immune complexes, thus leading to a deep dermal<unk>  vasculitis.
