Neonatal noma is a rare clinical syndrome affecting term and preterm infants. It causes gangrene of the orofacial tissues accompanied by sepsis and a high mortality rate. A preterm 35-week infant, severely growth retarded in utero, developed clinical signs of sepsis with ulcers all over the oral mucosa caused by local infection with Pseudomonas aeruginosa. The lesions healed with cicatricial sequelae of the mouth, sequestration of teeth, and retraction of perimandibular soft tissues.
