A case of Klinefelter's syndrome with acquired hypopituitarism.
The association of Klinefelter's syndrome (KS) and hypopituitarism has been described in previous isolated case reports, in most of which the hypopituitarism was partial. A case is described of a man with KS who acquired hypopituitarism in adult life. The diagnosis of KS was made at the age of 25 years on standard laboratory tests when he presented with failure of ejaculation and typical clinical features. Thirteen years later he presented with anaemia and further regression of secondary sexual characteristics. All aspects of anterior pituitary function were abnormal. The cause of the hypopituitarism was not determined, but may have been post-traumatic.
