The rarity of the congenital occurrence of pemphigus simplex or impetigo neonatorum seems to me to be reason enough to report and describe two cases that have come to my attention.
There is little in the literature on nonsyphilitic pemphigus. It is true that there have been a number of reports, but many of these do not stand critical analysis and appear to be examples of other conditions, such as toxic bullous eruption following the ingestion of drugs by the mother, epidermolysis bullosa hereditaria and congenital defects of the skin or traumatic denudations.
