A 24-year-old primigravid woman with adult type Gaucher's disease was admitted at 28 weeks of pregnancy. She was asthenic and the abdomen was markedly protuberant due to hepatosplenomegaly. A conservative approach with close monitorization of both mother and baby was planned. On the 39th week of pregnancy a healthy female baby of 3000 g was delivered via cesarean section. Apart from mild hematological complications, the pregnancy, the delivery and the puerperium were uneventful.
