The case of a 77-year-old woman with acute myeloid leukemia who developed Candida tropicalis septic arthritis of the knee after remission-inducing chemotherapy is reported. A literature review of C. tropicalis non-prosthetic arthritis is included. The isolate was susceptible to fluconazole (MIC 0.25 mg/l). She was treated with fluconazole (400 mg orally) and frequent relieving synovial aspirations. After 1 month of antifungal therapy the synovial fluid became culture negative. Fluconazole concentration in the synovial fluid and serum were 20 mg/l and 19.4 mg/l, respectively. The patient was treated for a total of 7 months and made a full recovery. This is the first report of the successful use of fluconazole in the treatment of septic arthritis due to C. tropicalis.
