ABSTRACT Maternal adrenal cortical carcinoma in pregnancy is rare. We report a case of an infant born to a mother with a history of adrenal cortical carcinoma. The pregnancy was complicated by fetal exposure to mitotane and dexamethasone. Despite the potential teratogenic exposures, there was no evidence of adrenal dysfunction in the infant. Growth and development at 12 months of age are normal and prognosis appears favorable. The long-term impact of fetal exposure to mitotane and glucocorticoid requires further investigation.

    ABSTRACT: Context:Adrenocortical carcinoma (ACC) affects patients in a broad age group, including young women. Mitotane, an adrenolytic agent, is the mainstay of treatment after surgical removal of the tumor. There is extreme paucity of information regarding the effect of mitotane on childbearing potential and pregnancy outcome.Objective:The aim of the study was to describe and discuss the case of an ACC patient who conceived while on mitotane treatment. Current literature is reviewed.Patient and Methods:A 33-year-old woman received mitotane treatment for 4 years due to metastatic ACC. Despite nearly therapeutic blood levels of the drug, the patient had regular menstruation and was able to conceive. Mitotane was stopped at gestation week 6. Although the drug continued to be detected in considerable amounts, the fetus developed normally, including morphologically intact adrenal glands. At gestation week 21, pregnancy was terminated due to ACC recurrence. Mitotane levels were undetectable in fetal cord blood and amniotic fluid.Conclusion:Our report suggests that mitotane, despite its action as an endocrine disruptor, does not affect normal gonadal function or an ability to conceive. The concern of placental transfer by this hydrophobic compound is not supported by our findings. However, we do not recommend drawing conclusions regarding the safety of mitotane in pregnancy, based on 1 or several case reports. Until more data are available, pregnancy should be avoided in women being treated with mitotane for ACC.
