Insights
A rare case of precocious puberty in a 15-month-old girl was likely caused by an ovarian cyst. Surgical removal of the cyst led to the regression of early pubertal development.
Area of Science:
- Pediatric Endocrinology
- Reproductive Endocrinology
Background:
- Precocious puberty (PP) is defined as the onset of secondary sexual characteristics before age 8 in girls and age 9 in boys.
- It can be classified as central (CPP) or peripheral (PPP), based on the source of gonadotropin stimulation.
Observation:
- A 15-month-old girl presented with rapid pubertal development including breast and pubic hair growth, a growth spurt, and vaginal bleeding.
- Initial presentation suggested central precocious puberty (CPP), but rapid progression and early menarche pointed towards peripheral precocious puberty (PPP).
- Hormonal assays showed low LH concentrations, indicative of PPP, yet the LH:FSH ratio was suggestive of CPP.
Findings:
- Abdominal imaging identified an ovarian mass, which was surgically removed.
- Histopathological examination of the mass revealed hemorrhage and ovarian torsion, with its exact nature undetermined.
- Post-operative regression of pubertal development was observed over three months.
Implications:
- This case highlights the diagnostic challenges in differentiating CPP and PPP, especially with unusual presentations.
- Autonomous ovarian cysts can be a rare cause of peripheral precocious puberty in young children.
- Surgical intervention for ovarian masses in cases of suspected PP can lead to resolution of symptoms.
Abstract:
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.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
