RESUMEN
@#Precocious puberty is defined as appearance of secondary sexual characteristics that begins earlier than usual, and may be central or peripheral in origin. It is the physician’s duty to undertake a detailed investigation of the cause of the condition so as not to overlook a potentially correctable pathologic lesion, and prevent long-term somatic and psychosocial consequences in the child. This paper presents a case of 10 year old female with clinical signs and symptoms and laboratory results that point to a possible peripheral type of precocious puberty , and with a huge ovarian mass, which intraoperatively yielded inconclusive histopathologic findings due to massive necrosis. This paper aimed to discuss the possible etiologies for the development of precocious puberty in the index case, and the treatment options for both precocious puberty and ovarian new growth.
