男性のプロラクチン産生下垂体腺腫—女性例との比較

Prolactin-secreting Pituitary Adenomas in Men: Comparison with Female Cases

I．はじめに

　男性のプロラクチン（PRL）産生下垂体腺腫は稀であるといわれ，その報告も女性例に比べると少ない．特に，男性例と女性例を比較した報告^5,6,39,44）は極めて少ない．そこでわれわれは，男性のPRL産生下垂体腺腫について，その臨床像，治療成績について女性例と比較検討したので，その結果を報告する．

PRL-secreting pituitary adenomas in men are generallyreported to be rare but we experienced with nine (21%)among 44 patients with PRL-secreting pituitary adenomas.We compared the difference between PRL-secreting pitui-tary adenomas in male and those in female patients.

Microadenomas were not found in male patients butthey were found in 54% of female patients. Suprasellarextension of adenomas occurred in 78% of male patients butin 34% of female patients.
