Diabetes Mellitus is recognized for its increased vulnerability to infections, notably cellulitis. This report presents a case of a 35-year-old male with a history of type 2 diabetes for three years. Following a minor bike accident, the patient's wound ended in cellulitis due to unmanaged diabetes and possible medical oversight. Initially, the wound was treated with tetanus toxoid and dusting powder. However, after a week, the wound worsened, showing signs of pus formation and significant swelling. Despite medical consultation, the absence of antibiotics led to a progression in symptoms and hospital admission. An elevated blood sugar levels was evident, with a glycated hemoglobin (HbA1c) of 8.5%. Subsequent therapeutic interventions, such as incisional drainage and intensive antibiotic therapy, led to stabilization. This case highlights the importance of vigilant wound management and therapeutic intervention in diabetic patients, emphasizing timely antibiotic administration to prevent complications.
