A 69-year-old man was admitted to hospital with a three month history of a diffuse eruption of painful crusted erythematous papulopustular lesions involving the face and neck. His medical history included chronic lymphocytic leukaemia on monthly intravenous immunoglobulin infusions, type 2 diabetes mellitus and a previous fungal lung abscess for which he was on prophylactic posaconazole. The eruption had not responded to two weeks of amoxicillin-clavulanate started by his general practitioner. By then, he had multiple haemorrhagic pustules (Fig. 1). Skin biopsies for histology and tissue culture demonstrated chronic inflammation with the presence of multiple demodex mites. Swabs from four pustules showed a light growth of normal skin flora.
