1/2. Congenital adrenal hyperplasia associated with maternal pregnancy luteoma and the Antley-Bixler syndrome.The authors report on a child with indifferent external genitalia consisting of severe micropenis with penile urethra leading to the tip of the glans and bilateral cryptorchidism. Diagnostic workup findings showed a female karyotype, homozygous 21-hydroxylase deficiency, and excessive testosterone exposure prenatally as a consequence of maternal pregnancy luteoma, altogether causing this unusual phenotype. In addition, the girl suffered from skeletal anomalies consistent with the diagnosis of Antley-Bixler syndrome. Our case shows that, although the association of congenital adrenal hyperplasia with other syndromes is rare, and even if other possible reasons for in utero virilization are present, complete diagnostic workup including karyotyping and hormonal status should be done in all patients with ambiguous genitalia, especially in cases of an unusual phenotype. The authors report on the diagnostic procedures and discuss the surgical approach in this particular case, never described before in the literature.- - - - - - - - - - ranking = 1keywords = karyotype (Clic here for more details about this article) |
2/2. prenatal diagnosis of female pseudohermaphroditism associated with bilateral luteoma of pregnancy: case report.female pseudohermaphroditism associated with luteoma of pregnancy (LP) is a rare condition characterized by varying degrees of masculinization of a female fetus. We describe a case, diagnosed at 13 weeks gestation. Transvaginal ultrasound at 5 weeks of gestation revealed a normal intrauterine gestational sac and an enlarged maternal right ovary. Re-examination at 13 weeks showed a fetus with male external genitalia. Cytogenetic investigation on amniotic fluid revealed a normal female karyotype 46,XX. Follow-up sonography confirmed the previous assignment of male external genitalia and a second amniocentesis was negative for the SRY gene. High levels of androgens were found in the maternal blood. A diagnosis of female pseudohermaphroditism associated with bilateral LP was made. A healthy girl was born by Caesarean section with complete masculinization of external genitalia (Prader V). histology confirmed a bilateral LP. To the best of our knowledge this represents the first case of prenatal diagnosis of female pseudohermaphroditism associated with LP and demonstrates the feasibility of diagnosis by sonography from 13 weeks gestation. This is also the first case described of Prader V masculinization associated with LP.- - - - - - - - - - ranking = 1keywords = karyotype (Clic here for more details about this article) |
