[Correlation of obstetrical and clinical data with nevi flammei in the newborn (author's transl)]. / Korrelation schwangerschaftsanamnestischer und klinischer Befunde mit dem Auftreten von Naevi flammei bei Neugeborenen

ABSTRACT

Nevus flammeus (teleangiectaticus) is the most common variety of congenital nevus. Among 3961 infants checked at the ages of 3--7 days and again at 6 weeks 42% showed nevi flammei mediales in the nape and/or in the eyelids and glabella. The mothers of the infants presenting with n.fl. tended to be overweight, to have circulatory distrubances and prolonged duration of laor. The infants with n.fl. frequently had concomittant edema, navel hernia and minor degenerative stigmata. However malformations did not occur more commonly. This investigation suggests that exogenous factors such as diseases during pregnancy, intake of drugs and difficulties in delivery do not influence the genesis of n.fl. Only constitutional factors could be correlated with the incidence of n.fl. Since there was a higher frequency in female than in male infants and a lower frequency in premature than in term newborns it may be that hormonal inffluences increase the incidence of n.fl., too. These results were obtained from the prospective study Schwanger-schaftsverlauf und Kindesentwickling (DFG).
