A 62-year-old woman presents to the emergency department complaining of three days of subjective fevers and chills. Her initial evaluation was notable for both a fever of 100.4°F (38°C) and an 8 cm-wide warm, erythematous, indurated rash on the right calf. The borders of this lesion were ill-defined. On palpation, the rash was tender and without any notable crepitus. The rest of the physical exam was unrevealing. Notably, her white blood cell count (WBC) was elevated to 17,900/µL (normal: 4,000-11,000/µL) with a differential of 86.8% neutrophils (normal: 50-70%) and 8.1% lymphocytes (normal: 18-42%). All other laboratory parameters were within normal limits. Following her emergency department evaluation, the patient is admitted to the hospital in stable condition.
