A patient with chronic progressive pulmonary aspergillosis was treated with itraconazole (ITCZ). However, owing to difficulty in controlling the disease, the treatment was changed to voriconazole (VRCZ). Nevertheless, VRCZ had to be discontinued 2 months after this change owing to agranulocytosis. After temporary discontinuation, VRCZ was resumed after the patient’s neutrophil counts had recovered; however, agranulocytosis reappeared 2 months later. The diagnosis was idiosyncratic drug-induced agranulocytosis (IDIA) caused by VRCZ. After switching from VRCZ to ITCZ, agranulocytosis had not recurred after more than 6 months. This case indicates that VRCZ may cause agranulocytosis, and switching to other azoles may be effective in such cases.
