Cushing's syndrome in pregnancy.

Fertility and childbearing rarely occur in Cushing's syndrome because amenorrhea, oligomenorrhea, infertility, and abortions characterize the disease. Currently, a total of 53 cases of Cushing's syndrome and pregnancy have been reported. When Cushing's syndrome occurs during pregnancy, approximately 56 per cent of the cases are associated with adrenal cortical adenoma or carcinoma. Excluding Cushing's disease, nearly 21 percent of the cases are caused by adrenal carcinoma. The maternal catabolic state of glucocorticoid excess contributes to poor fetal outcome with many of the cases complicated by either fetal wastage or prematurity. However, congenital malformations are not seen more frequently than in normal pregnancy. Pregnancy may or may not influence Cushing's syndrome, but Cushing's syndrome definitely complicates pregnancy.
