[Hereditary hypertension in Recklinghausen's disease during pregnancy. A family]

We report the case of a pregnant woman who presented with neurofibromatosis and hypertension the latter revealed by abruptio placentae. Severe hereditary hypertension was noted in the family during pregnancies that were sometimes complicated by intrauterine growth retardation, abruptio placentae and intrauterine foetal death. Thus, neurofibromatosis in a pregnant woman has a poor obstetrical outcome when it is associated with a personal or family history of hypertension. Such women must be treated with extreme care and hospitalized at the end of the third trimester. The advisability of prevention with low-dose aspirin during the first trimester is discussed.
