Hipertricosis cubital en una paciente con pubarquia precoz: Caso clmico / Hypertrichosis cubiti in a girl with precocious puberty: Case report

La hipertricosis cubital es un aumento localizado de la densidad, longitud y espesor del vello. Es una entidad benigna con muy escasos pacientes descritos en la literatura médica (alrededor de medio centenar). La mitad de los casos descritos asocian otros defectos o malformaciones, y la otra mitad son problemas puramente estéticos. La pubarquia precoz en niñas se define como el inicio del vello púbico antes de los 8 años de edad. Se presenta a una paciente de 6 años con la asociación no descrita previamente de hipertricosis cubital y pubarquia precoz.

Hypertrichosis cubiti is a localized increase in hair density, length and thickness. It is an uncommon and benign entity with very few patients described in the medical literature (more or less than half a hundred). Half of the described patients associate other defects or malformations and the other half are purely aesthetic cases. Early pubarche in girls is defined as the onset of pubic hair before 8 years of age. We present a six-year-old patient with the association not previously described of hypertrichosis cubiti and precocious pubarche.

Estrogen-mediated Height Control in Girls with Marfan Syndrome

This study evaluated the efficacy of a stepwise regimen of estradiol valerate for height control in girls with Marfan syndrome. Eight girls with Marfan syndrome who had completed estrogen treatment for height control were included. Estradiol valerate was started at a dose of 2 mg/day, and then was increased. The projected final height was estimated using the initial height percentile (on a disease-specific growth curve for Korean Marfan syndrome [gcPFHt]), and the initial bone age (baPFHt). After the estrogen treatment, the projected final height was compared to the actual final height (FHt). The median baseline chronological and bone age were 10.0 and 10.5 years, respectively. After a median of 36.5 months of treatment, the median FHt (172.6 cm) was shorter than the median gcPFHt (181.0 cm) and baPFHt (175.9 cm). In the six patients who started treatment before the age of 11 years, the median FHt (171.8 cm) was shorter than the median gcPFHt (181.5 cm) and baPFHt (177.4 cm) after treatment. The median differences between the FHt and gcPFHt and baPFHt were 9.2 and 8.3 cm, respectively. In two patients started treatment after the age of 11, the differences between FHt and gcPFHt, and baPFHt after treatment were -4 and 1.4 cm, and -1.2 and 0 cm for each case, respectively. A stepwise increasing regimen of estradiol valerate may be an effective treatment for height control in girls with Marfan syndrome, especially when started under 11 years old.
