Unsustained central sexual precocity in four girls.
Four girls who presented with breast enlargement at 4-5.8 years of age have been followed without specific therapy for up to 4 years. Three had normal CT brain scans, one had normal skull and sella x-rays. Stimulation of gonadotropins by LHRH was excessive in all but plasma estradiol levels were only intermittently elevated. Initially, bone age was advanced and height velocity was increased in three of the four. Ultrasound visualized an enlarged uterus in two and waxing and waning ovarian cysts in all. The clinical course was characterized by persistence of physical signs over at least 3.4 years in one patient, fluctuation in another, and marked regression in two. We propose that some patients with central precocious puberty may spontaneously have a nonprogressive course which has to be considered when evaluating the efficiency of drugs interfering with puberty.
