Sexual precocity in a boy due to hyper secretion of luteinizing hormone and prolactin by a pituitary adenoma






Acta Endocrinologica 102(2): 167-172

Sexual precocity in a boy due to hyper secretion of luteinizing hormone and prolactin by a pituitary adenoma

Precocious puberty and galactorrhea in a 4 yr 8 mo. old boy are discussed. Roentgenograms of the skull showed slight lateral bulging of sella floor and pneumoencephalography indicated a pituitary adenoma with a suprasellar extension. Pre-operative study of anterior pituitary function was normal except for increased values of LH [luteinizing hormone] (900 mIU/ml), testosterone (2000 ng/ml) and prolactin (215 ng/ml). After removal of a chromophobe pituitary adenoma by transfrontal surgery the galactorrhea disappeared within 10 days. Post-operative endocrine evaluation showed immediate normalization of LH, testosterone and prolactin values.
