cortodoxone and Hyperpigmentation

We describe a patient with signs and symptoms of virilization caused by 21-hydroxylase deficiency. The patient, a Hispanic woman, first sought medical attention at age 24, when she presented to a medical clinic with an uncomplicated urinary tract infection. At that time several signs of virilization were noted and she was referred to the endocrinology clinic. Evaluation revealed temporal balding, hyperpigmentation, acne, absent breast development, a muscular habitus, and clitoromegaly. Radiological studies revealed bilaterally enlarged adrenal glands and ovaries. Laboratory evaluation revealed markedly increased concentrations of 17-hydroxyprogesterone, androstenedione, and testosterone. The patient was diagnosed with congenital adrenal hyperplasia (CAH) and received hormone therapy. In her sister, encouraged to undergo testing for this autosomal recessive disorder, HLA testing demonstrated that certain haplotypes in this family were associated with CAH. The case highlights key steps in the laboratory diagnosis and genetics of CAH.
