Management and Outcome
Gender was reassigned female
Hydrocortisone (Cortef) and fludrocortisone acetate (Florinef) started along with NaCl supplements
On day 10 of life, weight 3.2 kg, feeding 4 oz/4 hours - By 4 months of age, significant reduction in clitoral and labial
enlargement as well as resolution of hyperpigmentation - By 3 years of age, the clitoral size had not normalized and
the mother became very concerned about the child showing
signs of gender “confusion,”and hence clitoral reduction
surgery was performed
