[1] [2] Lower legs and heels may also be involved, however the distal parts of feet and toes are usually spared. Patients may also experience high-graded fever, pitting edema and hypotension. The clinical presentation usually resembles cellulitis, however bilateral involvement is a differentiating feature.
Bilateral lower extremity inflammatory lymphedema (BLEIL) is a distinct type of lymphedema occurring in a setting of acute and prolonged standing, such as in new recruits during basic training. [28] Possible underlying mechanisms may include venous congestion and inflammatory vasculitis.
Edema may be described as pitting edema, or non-pitting edema. [32] Pitting edema is when, after pressure is applied to a small area, the indentation persists after the release of the pressure. Peripheral pitting edema, as shown in the illustration, is the more common type, resulting from water retention.
Leg edema Peripheral edema is edema (accumulation of fluid causing swelling) in tissues perfused by the peripheral vascular system , usually in the lower limbs . In the most dependent parts of the body (those hanging distally ), it may be called dependent edema.
Podoconiosis causes bilateral yet asymmetrical leg swelling with overlying firm nodules. Early on, symptoms may include itching, tingling, widening of the forefoot, and swelling which then progress to soft edema, skin fibrosis, papillomatosis, and nodule formation resembling moss, giving rise to the disease's alternate name of "mossy foot" in some regions of the world.

An example that illustrates the difference between SP and Stasis Papillomatosis and the histology diagnosis is: "a markedly obese, 41-year-old Japanese man who had suffered from psoriasis vulgaris for several years visited hospital with elephantiasis-like swelling of his lower legs of three months' duration.
The risk of lymphedema exists in 29 percent of patients, where leg swelling typically lasts 2 to 3 months. [14] Lymphedema can be caused by blockages in the lymphatic system, leading to insufficient lymph drainage and fluid build-up in the leg. Though it is incurable, swelling of the leg is usually temporary.
As functional venous valves are required to provide for efficient blood return from the lower extremities, this condition typically affects the legs. If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3]
