A 50-year-old man presented to our dermatology department with a 1-day history of bluish-purple tender plaques on his thighs. The patient was on the second cycle of consolidation chemotherapy for acute myeloid leukaemia (AML) secondary to myelodysplastic syndrome (MDS), and had neutropenia as a result of this treatment. He was on intravenous vancomycin and imipenem for the treatment of methicillin-resistant coagulase-negative staphylococcal bacteraemia. On physical examination, purple plaques were found over the patient's left lateral thigh and on the medial right thigh without fluctuation (Fig. 1). The plaques were extremely tender to light touch, but there were no signs of sepsis. Axillary temperature was 37.4°C, heart rate was 88 beats ⁄ min, and blood pressure was 110 ⁄ 75 mmHg. Incisional biopsy specimens were obtained from the plaques on the right and left thighs.
