Intestinal zygomycosis due to Absidia corymbifera mimicking necrotizing enterocolitis in a preterm neonate.

Zygomycosis is a rare fungal disease that occurs in compromised human hosts, including the preterm infant. The three clinical forms of zygomycosis are cellulitis, disseminated, and gastrointestinal, and the last often mimics necrotizing enterocolitis (NEC), complicating the diagnosis. This report details a case of primary gastrointestinal zygomycosis due to Absidia corymbifera, mimicking NEC, in a preterm infant, and emphasizes features that may lead to earlier diagnosis and treatment of future cases.
