Chronic Venous Insufficiency: This condition is characterized by the veins' inability to send blood back to the heart from the legs, leading to fluid buildup and edema. Leaking edema, often seen as weeping or oozing from the skin, can occur due to the increased pressure and fluid accumulation.

Lymphedema: A condition where the lymphatic system is impaired, leading to the accumulation of protein-rich fluid in the interstitial tissue, causing swelling. Leaking edema can be a complication of severe, untreated lymphedema.
Cellulitis with Venous Ulceration: An infection of the skin and subcutaneous tissues that can lead to ulceration, especially in the context of chronic venous insufficiency. The ulceration can cause leaking edema.
Deep Vein Thrombosis (DVT) with Post-Thrombotic Syndrome: While DVT itself may not directly cause leaking edema, post-thrombotic syndrome, a complication of DVT, can lead to chronic venous insufficiency and subsequently to leaking edema.

Necrotizing Fasciitis: A severe infection that destroys the tissue under the skin, including fat and the tissue covering the muscles (fascia). It requires immediate medical attention and can present with edema, though leaking edema might not be the primary symptom.
Gas Gangrene: A potentially deadly condition resulting from infection with Clostridium perfringens, characterized by tissue death and gas production. Early signs can include swelling and edema, though leaking edema is not the hallmark.

Lipedema: A chronic condition characterized by the abnormal growth of fat cells in the legs, leading to swelling. While it can cause significant discomfort and swelling, leaking edema is less commonly associated with lipedema compared to other conditions.
Myxedema: A condition associated with hypothyroidism, characterized by thickening of the skin and underlying tissues due to the accumulation of mucopolysaccharides. It can cause swelling but is less likely to cause leaking edema from the legs.
