Intestinal candidiasis: An uncommon cause of necrotizing enterocolitis (NEC) in neonates

Candida albicans produces intestinal perforation and necrotizing enterocolitis (NEC) in preterm newborns. We reviewed pathology files in neonates with a diagnosis of NEC (10-year period), gathered history, and reviewed histological materials. Of 249 autopsies, two (0.8%) had systemic candidiasis. From 66 surgical cases with a diagnosis of NEC, five cases (7.5%) had intestinal candidiasis. Candida albicans grew in pre- and post-mortem blood, lung, or peritoneal fluid in all cases. Histologically, the small bowel revealed fungi, sometimes intravascular. Systemic candidiasis with intestinal involvement is an important complication of prematurity and a prevalent cause of sepsis. The presence of intraluminal fungi with associated vascular occlusion may lead to bowel ischemia, necrosis, and perforation.
