Dermatologic manifestations of infectious diseases in pregnancy.

Several pathogens that have been identified as teratogenic or fetotoxic have associated dermatologic changes when active infection is present. Viral and bacterial teratogenic pathogens include herpes simplex virus 1, herpes simplex virus 2, varicella-zoster virus, cytomegalovirus, human papilloma virus, human parvovirus B19, rubella, viral hepatitis, syphilis, and gonorrhea. This article focuses on the characteristic dermatologic manifestation of these diseases in pregnancy; diagnostic strategies; interpretation of maternal and fetal laboratory test results; treatment of the pregnant woman, fetus, and newborn; and congenital outcomes of treated and untreated infection. Emphasis is placed on vaccination and prevention of transmission of infection to pregnant women.
