title: A patient with Klinefelter's syndrome and thalassemia intermedia.
abstract: Klinefelter's syndrome (KS) is associated with a wide spectrum of clinical features, such as tall stature, eunuchoid proportions, testes disproportionately small for the level of pubertal development, gynecomastia and behavioral problems. The association of KS with thalassemia intermedia has not been previously reported. A male patient with thalassemia intermedia was diagnosed with KS at the age of 14 years when endocrine evaluation for delayed puberty showed hypergonadotrophic hypogonadism. Thyroid function was normal; however, basal and GnRH-stimulated gonadotropin concentrations were raised while serum testosterone was low. Karyotype analysis revealed KS (47,XXY). Testosterone replacement therapy started soon after diagnosis and now at the age of 20 years the patient's height is 178.3 cm, the U/L ratio is 0.91. Testicular volume is 12 ml (Prader orchidometer) and his pubic hair is stage 4. To our knowledge this is the first case of a patient suffering from KS and thalassemia intermedia reported in the literature.
