Comprehensive and Detailed Explanation:

Venous leg ulcers classically occur in the gaiter region, most often near the medial malleolus. They have irregular borders, a red or fibrinous base, moderate to heavy exudate, and are accompanied by hemosiderin staining, varicose veins, and edema. Pulses are usually present unless mixed disease exists. Arterial ulcers favor distal locations, appear punched-out, and occur with diminished pulses. Pressure injuries develop over bony prominences in immobile patients. Neuropathic ulcers occur on pressure points of the insensate foot. Correct etiological classification is fundamental because it dictates first-line therapy: compression for venous disease, revascularization consideration for arterial disease, pressureredistribution for pressure injuries, and offloading for neuropathic ulcers. Misidentification leads to ineffective or harmful treatment.
