Cornual pregnancy is a rare entity associated with high morbidity and mortality. Diagnosis is challenging because the embryo usually appears on ultrasound as localized inside the uterus. Cornual pregnancy is more dangerous than other ectopic pregnancies, and cornual rupture may lead to severe maternal hemorrhage. It has the same risk factors as tubal pregnancy. Early diagnosis allows either medical treatment with methotrexate or conservative surgical treatments. We present a case of cornual pregnancy with unusual evolution to a single dose of methotrexate.

Cytomegalovirus (CMV) is the leading cause of congenital infection in developed countries, affecting 0.3 to 0.6% of all live births in Europe. Primary CMV infection occurs in 1 to 4% of seronegative women during pregnancy and may be transmitted to the fetus in 40% of cases. Up to 10% of intrauterine CMV infections result in symptomatic congenital disease at birth. Half of these children and 13% of those born with asymptomatic infection will develop long-term sequelae, especially neurosensory hearing loss and mental retardation. Accurate diagnosis of primary maternal and fetal infection is now possible using the avidity index of anti-CMV IgG and virological testing to detect the virus in amniotic fluid. The gold standard for diagnosis of congenital CMV infection is the detection of the virus in urine within the first 2 weeks of life by rapid cell culture techniques (shell vial) or nucleic...

La micosis fungoide es una neoplasia maligna originada en los linfocitos T. Usualmente inicia con la aparición de manchas planas o estadio de mancha. Con el correr de los años, las lesiones van siendo infiltrantes, apareciendo las placas o estadio de placas. Presentamos a un paciente de sexo femenino de 50 años con hallazgos clínicos e histopatológicos de micosis fungoide en estadio eritematoso o manchas a nivel de vulva.

Heterotopic pregnancy is the simultaneous development of an intrauterine and an ectopic pregnancy. This complication is increasing due to infertility treatment, especially assisted reproduction techniques. There are two types: induced (associated with in vitro fertilization techniques, rate 1:1 000 to 1: 1 500 pregnancies) or spontaneous (1:20 000 to 1:80 000 pregnancies). Causal factors for spontaneous heterotopic pregnancies include pelvic inflammatory disease, use of intrauterine device or hormonal devices, previous pelvic surgery, and history of ectopic pregnancy. We present two cases of spontaneous heterotopic pregnancies.

An aberrant right subclavian artery (ARSA) is the most common branching abnormality of the aortic arch. It can be identified by ultrasound scan in 1% of the cases. The probability of association with cardiac and/or extracardiac anomalies, as well as chromosomal abnormality, is high. The prevalence of ARSA with Down syndrome is approximately 20%, and this marker may contribute to counseling in Down syndrome during the second trimester and maybe in the first trimester. Recommendations when finding an ARSA is to carry out a detailed study of the fetal anatomy looking for other markers of the aneuploidy and to perform a fetal echocardiogram. The performance of invasive studies will be limited to those situations where, in addition to the ARSA, other markers or other conditions that increase the risk of Down syndrome are found. However, the finding of an isolated ARSA increases the risk to ze...

Congenital heart disease is the most common congenital anomaly. Ventricular septal defect (VSD) is a frequent congenital heart disease in newborns, affecting 25 to 30% neonates with cardiac defects. Muscular VSDs are more frequent than perimembranous VSDs. The association of cases with chromosomal anomalies and isolated VSD is relatively low. Spontaneous closure of isolated VSD is higher with small VSD cases, and the muscular VSD is more likely to close spontaneously than the membranous or perimembranous types. Therefore, diagnosis of isolated muscular VSD with no other anomalies can be considered a benign finding.

Herlyn-Werner-Wunderlich syndrome is a rare congenital anomaly of the urogenital tract caused by defective fusion of the Müllerian ducts, which gives rise to obstructed hemivagina, uterus didelphys and ipsilateral renal agenesis. We report the case of a 16-year-old girl who underwent resection of the vaginal septum and drainage of the secondary hematocolpos, thus preserving her reproductive function.

Ovarian cysts are the most common abdominal tumors in female newborns. Among the acute and long-term complications, the most frequent is the adnexal torsion, which is difficult to recognize in the neonatal stage. Prenatal diagnosis is essential for the timely management of patients and ultrasound monitoring of adnexal cysts. There are different therapeutic alternatives where minimally invasive and conservative surgery plays an important role.
