ABSTRACT
Precocious puberty is defined as children attaining puberty more than 2.5 to 3 standard deviations (SD) earlier than the median age, or before the age of eight years in girls and nine years in boys. Hypothalamic hamartoma (HH) are rare, non progressive tumor like malformation. Precocious puberty due to HH occurs particularly at early ages, even 2 or 3 years. Treatment options for isolated CPP due to HH include GnRH analogs agonists continuously stimulates pituitary gonadotrophs, which further help in decreasing and desensitizing the release of LH, and to a lesser extent, FSH till the time puberty naturally set in. We present a case of precocious puberty due to hypothalamic hamartoma in 3 years old girl. Treated with GnRH analog lupirode and responded well to treatment with cessation of menstruation and reduction in breast size.
