[Neonatal varicella: report of a case of bronchopneumonia and hemorrhagic pulmonary edema].

We describe the case of a male newborn infant, whose mother developed varicella 20 days before delivery. At 2 hours of life the infant's general state suddenly deteriorated and he presented cyanosis, respiratory distress and emission of pink foam in his mouth. The infant was diagnosed with bilateral bronchopneumonia, of probable varicellosus etiology, with a component of hemorrhagic pulmonary edema. He required mechanical ventilation and inotropic support for 48 hours. Response to endovenous acyclovir was favorable. At 10 days of life varicella-zoster virus (VZV) in cerebrospinal fluid was detected by polymerase chain reaction and seroconversion of IgG anti-VZV was positive.
