ResumenIntroducción: Los tumores de las células de la granulosa de tipo juvenil (TCGJ) son muy poco frecuentes, especialmente en menores de 1 año. Los signos de pubertad precoz constituyen la presentación clínica más importante. Objetivo: Presentar una lactante con pubertad precoz periférica, con diagnóstico de TCGJ, discutiendo las claves de su tratamiento y seguimiento. Caso Clínico: Lactan… Show more
“…The occurrence of true PP in girls below one year of age is rare, and most cases described in the literature were due to an ovarian neoplasm [7,8,11,12]. To the best of our knowledge, ours is the first infant to develop PP due to an autonomous ovarian cyst.…”
We present a rare occurrence of precocious puberty (PP) probably due to an autonomous ovarian cyst in a 15-month-old girl who presented to us with growth spurt, breast and pubic hair development, and vaginal bleeding over the last few months. The clinical presentation was suggestive of central precocious puberty (CPP). However, the rapid progression of pubertal changes and occurrence of menarche at breast Tanner stage 2 indicated peripheral precocious puberty (PPP). Due to uncertainty of clinical diagnosis, investigations were conducted for CPP as well as PPP. The basal and peak stimulated LH concentrations were < 0.3 IU/l and < 2 IU/l, respectively, indicating PPP. However, the peak LH : FSH ratio was > 1, which is consistent with CPP. Abdominal imaging revealed an ovarian mass, which was laparoscopically excised, but the true nature of the mass could not be ascertained because the excised specimen showed only haemorrhage and features of ovarian torsion on histopathological examination. Regression of pubertal development occurred over a three-month period postoperatively.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
