Precocious puberty (Latin: pubertas praecox) is an unusually early onset of puberty, the process of sexual maturation triggered by the brain or exogenous chemicals, which usually begins in late childhood and results in reproductive maturity and completion of growth. Early puberty may be a variation of normal development, or may be a result of a disease or abnormal hormone exposure.
In some contexts, the term is used more broadly to describe the early appearance of any of the physical features of puberty even if the complete brain-directed process is not occurring.
Early pubic hair, breast, or genital development may result from natural early maturation or from several other conditions.
Early sexual development deserves evaluation because it may:
Central precocious puberty can be caused by intracranial neoplasm, infection, trauma, hydrocephalus, and Angelman syndrome.[1]
High levels of beta-hCG in serum and cerebrospinal fluid observed in a 9-year old boy suggest a pineal gland tumor. The tumor is called a chorionic gonadotropin secreting pineal tumor. Radiography and chemotherapy reduced tumor and beta-hCG levels normalized.[2] “Central precocious puberty (CPP) was reported in some patients with suprasellar arachnoid cysts(SAC) [3], and SCFE occurs in patients with CPP because of rapid growth and changes of growth hormone secretion.”[3]
Bones can be considered older in individuals with early puberty beyond actual age of individual. Early puberty is marked by growth hormone problems resulting from various brain disorders.
