Candida arthritis in patients with a haematological malignancy is rare. We report a case of Candida tropicalis arthritis of the knee that occurred in a patient with acute lymphoblastic leukaemia during the recovery phase of post-chemotherapy neutropenia. Although the Candida tropicalis isolates from synovial fluid and synovial tissue were sensitive to fluconazole in vitro, a 6-week course of oral treatment failed to produce clinical improvement. The arthritis resolved after 7 weeks of combination therapy with caspofungin, a new echinocandin class of antifungal agent that acts primarily on the cell wall. Eleven other reports of Candida arthritis in patients with a haematological malignancy were reviewed.
