Teratogenic effects in a case of maternal treatment for acute myelocytic leukaemia--neonatal and infantile course.

Experience with the use of cytotoxic drugs in the first trimester of pregnancy is limited. We report on the clinical phenotype and infantile development of a girl born to a 36-year-old mother. Before recognition of pregnancy, the latter had been treated for acute myelocytic leukaemia receiving cytarabine, daunorubicin and doxorubicin at conception and cytarabine and thioguanine at about 35-37 days post conception. At delivery, there were severe brachycephaly, hypoplasia of the anterior cranial base and the midface as well as synostoses of both coronal and metopic sutures. Further findings included bilateral four-finger hands with hypoplastic thumbs and absent radii. This phenotype is reminiscent of the Baller-Gerold syndrome. The child, at present 15 months old, has had to undergo two operations for fronto-orbital advancement because of insufficient growth of the mid-face, nasal airway hypoplasia and increased intracranial pressure. Motor milestones are slightly retarded--neurodevelopment is otherwise normal. These findings are discussed in the context of the few previous reports and are particularly important for future genetic counselling.
