Precocious puberty is when a child's body begins changing into that of an adult puberty too soon. When puberty begins before age 8 in girls and before age 9 in boys, it is considered precocious puberty. Puberty includes rapid growth of bones and muscles, changes in body shape and size, and development of the body's ability to reproduce. The cause of precocious puberty often can't be found.
Metrics details. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. The patient was diagnosed with TS at the age of 4 years, upon a diagnostic work-up for dysmorphic features. She presented with normal height and normal growth velocity so that Growth Hormone GH therapy was not started. She was referred to our Department at the age of 7 years and 10 months, because of vaginal bleeding.
[Precocious puberty in boys. Study of a series of 34 cases]
Precocious puberty should be considered when secondary sexual characteristics appear before 8 years of age in girls and 9 years in boys. It results in accelerated skeletal development and sometimes a reduced adult height, and may have a psychosocial impact, especially due to early menses in girls. Two forms exist: gonadotropin-dependent precocious puberty GDPP; due to premature activation of the hypothalamo-pituitary-gonadal axis and gonadotropin-independent precocious puberty GIPP; due to autonomous secretion of sex steroids.
