Vaginal adenosis in a non-diethylstilbestrol-exposed 6-year-old patient

Abstract

Vaginal adenosis is rare, and it is defined as the presence of metaplastic cervical or endometrial epithelium within the vaginal wall. It is associated with in utero exposition to diethylstilbestrol and a high risk of vaginal carcinomas. A case of vaginal adenosis arising in a non-diethylstilbestrol-exposed 6-year-old patient is presented. Few cases have been described in children and adolescents, and since the withdrawal of diethylstilbestrol from the market, this condition is rarely described in the medical literature. However, it should be considered as a possible diagnosis in girls with persistent vaginal discharge.
