We describe the case of a 59-year-old renal transplant recipient who presented with sepsis and bilateral pulmonary emboli due to Candida parapsilosis. She was treated with intravenous caspofungin and had a transoesophageal echocardiogram, which revealed vegetations on her pacemaker leads. She then underwent surgery to replace her pacemaker; however, her blood cultures remained positive for C. parapsilosis postoperatively. Her antifungal was switched to liposomal amphotericin B and flucytosine for 6 weeks, which yielded sterile blood cultures, and she was then initiated on lifelong fluconazole. Her recovery was complicated by tacrolimus toxicity 1 month after discharge due to fluconazole-induced CYP3A inhibition.
