RESUMEN
Silver Russell Syndrome (SRS) is a rare condition (1/3000 - 1/100,000 newborns). We present a female infant with SRS, cardiac malposition and asymmetric enlargement of the clitoris. She is the first child of Greek nonconsanguinous parents, born at 38 weeks gestation, following in vitro fertilisation (IVF). The patient had intrauterine growth retardation, body asymmetry, enlarged clitoris, hemihypertrophy of external genitalia and features characteristic of SRS. Electrocardiography and chest X-rays revealed a median position of the heart. The infant fulfilled the criteria proposed by Price et al for SRS. Genetic analysis did not reveal mUPD of chromosome 7. This is the first report of a patient with SRS presenting ìmesocardiaî and asymmetric enlargement of the clitoris. Our case constitutes another paradigm of SRS following IVF, which possibly supports the hypothesis that IVF may be associated with higher prevalence of SRS than natural fertilisation.
