Primary aldosteronism due to a malignant ovarian tumour.

The case of a woman with autonomous aldosteronism, hypertension, and malignant ovarian tumour is reported. Hormone studies revealed high plasma aldosterone levels, and low plasma renin concentration. Following surgical removal of a malignant sex cord stromal tumour, the hyperaldosteronism regressed, and the hypertension improved. Subsequently the tumour recurred, as did hyperaldosteronism.
