A 70-year-old man presents with a history of varicose veins and recent onset of a painful, swollen leg. On examination, there is an open, weeping ulcer above his medial malleolus. What could be the potential cause, and what are the next steps?
The patient's symptoms and findings suggest a venous stasis ulcer, often associated with long-standing varicose veins and chronic venous insufficiency. The next step would be to confirm the diagnosis with a Doppler ultrasound to assess venous insufficiency and look for any evidence of deep vein thrombosis. Treatment typically involves compression therapy to promote healing of the ulcer, along with wound care. More severe or non-healing ulcers may require more advanced wound care therapies or surgical intervention.
