Answer

Premature adrenarche and premature thelarche are two common, benign, normal variant conditions that can resemble true precocious puberty but that progress slowly or not at all. Premature thelarche refers to the isolated appearance of breast development, usually in girls younger than 3 years; premature adrenarche refers to the appearance of pubic hair without other signs of puberty in girls or boys younger than 7-8 years. A thorough history, physical examination, and growth curve review can help to distinguish these normal variants from true sexual precocity. A review of this topic was published as an American Academy of Pediatrics clinical report. [1]
