We report three cases of fungal peritonitis in patients undergoing CAPD, representing 1.3% of 228 episodes recorded during an 8 year period. The three patients, who had been catheterized for a long time, had previous episodes of bacterial peritonitis and had received antibiotic therapy. The culture was decisive to make the diagnosis. The change of the catheter and the treatment with antifungal agents contributed to cure the infection, although the three patients died from other causes. One case of peritonitis was caused by Candida lusitaniae.
