[Lichen sclerosus et atrophicus as a cause of genital lesions in a girl].

In a 10-year old girl with irritated vulva lichen sclerosus et atrophicus (LSA) was diagnosed. She was successfully treated with local application of equal amounts of a cortisol ointment and zinc oil. LSA is a disease of the skin infrequently seen in children, and then mostly in girls. Diagnosis is based on typical lesions in the anogenital region (sharply delineated ivory discoloration, moderate sclerosis and atrophy, haemorrhagic erosions). Knowledge of this disease is important in order to distinguish it from sexual abuse.
