Fetal varicella syndrome.

Fetal varicella syndrome is a rare condition of the newborn, presenting with cutaneous scars, limb defects and ocular and central nervous system abnormalities. It is due to varicella or zoster developing in the fetus following maternal varicella infection during early pregnancy. We are reporting one such patient who presented with a linear, depressed, erythematous scar over the left forearm and axillary fold, with a history of maternal chicken pox during the first trimester of pregnancy.
