Lesioni cutanee stellate e simmetriche in un gemello “rimasto solo”

The incidence of multiple pregnancy has increased, particularly because of the advances in assisted reproductive technologies. Multiple gestations are high risk pregnancies, especially the monochorionic ones. Two/thirds of initially twin pregnancies result in singles at birth, a condition defined as vanishing twin syndrome. The intrauterine death of one of the twins can cause direct fetal damage to the surviving one on several levels. The paper describes the case of a child born from twin pregnancy that was interrupted for one of the co-twins at early second trimester of gestation who presented with aplasia cutis congenita.
