Introduction:

Congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency is an infrequent autosomal recessive disease and the associated cardiovascular complications in the advanced stages make the management even more complex.

Case presentation:

A male patient who starts pubarche at 2 years old, therefore, he is diagnosed with congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency, and subsequent hypertension from age 5. At eight-years-old, he is hospitalized for a foodborne illness that causes adrenal insufficiency. Additionally, he is diagnosed with peripheral precocious puberty, melanoderma, hypokalemia and left ventricular hypertrophy. He required stress dose of hydrocortisone and five antihypertensives.

Discussion:

Treatment determines a patient’s prognosis. Therefore, once precocious puberty and hypertension produce irreversible complications such as deterioration of the final height and left ventricular hypertrophy respectively, the management is extremely difficult.
