Two rare endocrinological diagnosis in one patient.

Acromegaly is a rare disorder with incidence of 3-4 patients per million per year (1). Klinefelter syndrome (KS) is the most common sex chromosome disorder occurring in about 1/500th live male births (2).The coincidence of multiple endocrinopathies is rare, but possible. We report the case of a 33 years old man diagnosed with both of those rare conditions - acromegaly and 47, XXY Klinefelter syndrome.
