Q. A 36-year-old man gets admitted to the hospital for a 5-day history of high fever and swollen left foot. He says that a week ago, he stepped on a rusted screw nail while fixing the furniture and injured his foot. Two days after this incident, he developed a fever and swelling of his injured foot for which he took over-the-counter medication. As the symptoms are worsening, he came to the hospital. His medical history shows that he is a known case of Type I diabetes mellitus for the past 20 years and is taking insulin. He has been admitted twice for diabetic ketoacidosis in the past. His temperature is 101°F (38.3°C), pulse is 98/min, blood pressure is 110/70 mmHg, and respirations are 15/min. Physical examination shows an erythematous swollen left foot extending up to the lower 1/3rd of the leg. Few ruptured bullae are present over the foot with no active discharge. The foot is warm and tender to the touch. Swollen tender red streaks are noted on the left foot. Left-sided popliteal lymph nodes are enlarged. There is no crepitus. Lab investigations are shown below. What is the most likely diagnosis for this patient based on his clinical features and lab results?
