Precocious puberty associated with a pineal cyst: is it disinhibition of the hypothalamic-pituitary axis?

Accelerated development of secondary sexual characteristics or sexual precocity is a well-known entity. Most authors recognize two groups of patients, those described as having central precocious puberty (CPP) and those with precocious pseudopuberty. CPP results from premature activation of the hypothalamic-pituitary-gonadal axis and pseudopuberty is caused by lesions that secrete gonadotropin-like substances or hormones.
