The goal of genital correction surgery is to create a cosmetic and functional outcome preserving the sensitivity. A case of correction for hypertrophy of the clitoris and labia majora is described. A 46 years old women, diagnosed at infancy with X0/XY mosaicism, presented in early childhood, hypertrophy of clitoris and labia majora. She underwent surgery to remove gonads in infancy, but she asked for reduction clitoroplasty and labia majora only after a long psicotherapic support. A small area of the clitoris to be preserved was marked. Neurovascular bundle was carefully separated from the corporal tissue that was cut off. Later the estimated amount of skin and fat to be removed from labia majora was marked. At 12 months after surgery, the patient's external genitalia had reached a normal appearance. The sensitivity of the surgically reduced clitoris had preserved and labia majora aspect had a good cosmetic result. © Capsula Eburnea, 2010.
