[Transitory precocious puberty caused by autonomous ovarian cysts. Clinical, endocrinologic and sonographic course]

Precocious pseudopuberty in girls may be due to autonomous ovarian cysts. The spontaneous course in two girls aged 3.5 and 5.75 years is described. For differential diagnosis of the precocious pubertal development the following parameters were particularly helpful: growth curves, bone age determinations, repeated LHRH tests and serial sonographic examinations of ovaries and uterus. Since spontaneous regression of pubertal signs could be seen after a few weeks with complete resolution of the ovarian cysts and endocrinological parameters returning to normal after a few months, laparotomy and ovariectomy could be avoided in these two patients.
