Abstract: Tumors are rare, but well-documented causes of precocious puberty in both sexes. The therapeutic and prognostic implications of a diagnosis of cancer require that the presence of a neoplastic process be ruled out in any case of precocious puberty. Granulosa-cell tumor of the ovary and Leydig-cell tumor of the testis are the most frequent gonadal tumors inducing precocious pseudopuberty in the two sexes. Adrenal tumors sustain a variety of endocrine syndromes, the most frequent one being virilization with or without hypercortisolism. Pure feminizing adrenal neoplasms have been described.For reasons not yet well understood, hypothalamochiasmatic glioma (β-HCG) secreting tumors have almost never been described in association with female precocious puberty. Among these neoplasia, pineal germ-cell tumor inducing sexual maturation must be included.Hypothalamochiasmatic glioma and chraniopharyngioma are the two cerebral tumors capable of inducing true precocious puberty. Even if equally distributed between both sexes, these tumors interfere with sexual maturation less frequently in girls than in boys.Hypothalamic hamartoma is considered a benign tumor, since it does represent a space-occupying mass. It more correctly could be called a malformation if its histologic characteristics are recalled. This cerebral lesion is now frequently described in children with true precocious puberty, probably because of improved diagnostic imaging methods.
