Alternaria alternata peritonitis in a patient undergoing continuous ambulatory peritoneal dialysis.

Fungal peritonitis is a serious complication of peritoneal dialysis (PD) leading to loss of ultrafiltration and discontinuation of PD treatment. The most frequently isolated fungi are Candida albicans and, filamentous fungi such Alternaria alternata species are found only rarely. We report the case of a 75-year-old woman who developed peritonitis due to this black fungus.
