[Pheochromocytoma and pregnancy. Report of two cases (author's transl)].

We found in the literature 119 cases of pheochromocytoma manifested during pregnancy and observed 2 personal cases. Pheochromocytoma and pregnancy show reciprocal influences. Unsuspected diagnosis is frequent and followed by a high maternal mortality. The tumor was surgically removed in 42 cases. There are two different attitudes: when diagnosed in early pregnancy, the tumor can be excised without delay although the foetal risk is high; when the diagnosis is made in the last trimester, foetal maturity has to be awaited to perform a combined caesarean section and excision of the tumor.
