A 76-year-old man with malignant fibrous histiocytoma was admitted for failure to thrive following 2 courses of chemotherapy. On hospital day 2, treatment with vancomycin was started for Staphylococcus bacteremia. In light of an elevated creatinine level and a vancomycin trough level of 63.3 μg/mL (normal, 5-10 μg/mL), the vancomycin was not administered on hospital day 10. Nine days later, the patient developed painful blistering on his palms bilaterally (vancomycin trough level, 22.6 μg/mL).
