Case report: 17 alpha-hydroxylase/17,20-lyase deficiency: A rare cause of endocrine hypertension

The combination of hypertension, hypokaliemia, and male pseudohermaphroditism or amenorrhea must prompt a search for a rare adrenal enzymatic defect, 17 alpha-hydroxylase/17,20-lyase deficiency. This is a report of the observation of a male patient in whom this rare deficit was diagnosed in adulthood on the basis of lifelong ambiguous external genitalia, hypogonadism, severe hypertension, bilateral adrenal hyperplasia, and biological markers evoking an excess of mineralocorticoids without hyperaldosteronism.
