Twenty years of dysuria in a patient with Addison's disease: a case report.

X-linked adrenoleukodystrophy is an X-linked recessive disorder affecting approximately 1 in 21,000 males, and is estimated to be the cause of adrenal insufficiency in approximately 35% of patients with idiopathic Addison's disease. The disease is caused by defective beta-oxidation of fatty acids in peroxisomes that leads to elevated serum concentrations of very-long-chain saturated fatty acids. The accumulation causes a primary adrenal insufficiency and progressive neurological dysfunction.
