Background.- Herpes gestationis in the neonate is usually associated w
ith an increased risk of premature birth and/or low birth weight for g
estational age (GA) and sometimes skin lesions. Neurologic manifestati
ons are nos described in these babies. Case report.- A boy was born at
35 weeks of GA from a mother who developed skin eruption typical of h
erpes gestationis. His weight was 2320 g and his height was 46 cm. He
had transient respiratory distress syndrome and was given antibiotics
due to suspected group B streptococcus injection. He developed on day
3 skin vesiculous eruption which disappeared within 3 days and neurolo
gic manifestations: hypertonia and hyperkinesis, abnormal EEG. The CSF
was normal. The manifestations spontaneously disappeared within 5 day
s. The herpes gestationis factor was present in both mother and infant
. Conclusion.- A relationship beetween the maternal herpes gestationis
and neonatal neurologic manifestations is possible; there was no othe
r known causes for the transient neurological disease.
