Write answer in between .Q:A 57-year-old man presents with a large wound on his right lower leg that has been present for 6 months as shown in the picture. He has had chronically swollen legs for over 10 years. His mother and brother had similar problems with their legs. He had a documented deep vein thrombosis DVT in the affected leg 5 years earlier, but has no other past medical history. He has a blood pressure of 12684 and heart rate of 62min. Which of the following is the most likely diagnosis?? A: Arterial ulcer, B: Marjolin ulcer, C: Chronic venous insufficiency, D: Lymphedema, E: Kaposi sarcoma,  <response>: Based on the information provided in the question stem, the key facts are:- 57-year-old man with a large wound on his right lower leg that has been present for 6 months - He has had chronically swollen legs for over 10 years- Family history of similar leg problems in mother and brother- History of DVT in the same leg 5 years ago- No other significant medical history- Normal blood pressure and heart rateThis sounds most consistent with chronic venous insufficiency leading to venous ulceration. The chronic leg swelling for over 10 years along with a family history and personal history of DVT in the same leg point to underlying venous disease. The large ulcer is likely a venous ulcer that developed due to the longstanding venous hypertension.The other choices can be ruled out:- Arterial ulcer - would see signs of peripheral arterial disease, unlikely with normal BP and pulse- Marjolin ulcer - ulcerating squamous cell carcinoma, no mention of precursor lesion- Lymphedema - possible, but less likely than venous given DVT history- Kaposi sarcoma - seen in immunocompromised patients, no risk factors identifiedC: Chronic venous insufficiency
