Congenital adrenal hyperplasia due to 11-beta-hydroxylase deficiency with skeletal abnormalities.

Classic congenital 11-beta-hydroxylase deficiency is a relatively uncommon cause of congenital adrenal hyperplasia and is characterized by virilization and often hypertension. The association of skeletal abnormalities (short metatarsal bone) and pulmonary stenosis in a patient with 11-beta-hydroxylase has been reported by our group. In this report, three new patients with congenital adrenal hyperplasia due to a defect in 11-beta-hydroxylase enzyme with short fourth metatarsals are described. Gynecomastia was noted in one patient. The relative rarity of 11-beta-hydroxylase deficiency and the association of skeletal abnormalities suggest the possibility that this is more than a mere coincidental finding.
