Marked Neonatal Breast Hypertrophy in a Male with Transient Hyperprolactinemia
男嬰之暫時性高催乳素血症與顯著之新生兒期乳房肥大：一病例報告
摘要
一足月在出生之初已呈顯著之兩側性乳房肥大。出生後廿一日之內分泌評估顯示清雌素酮，甲促素，甲狀腺素，睪丸脂酮，絨毛膜 性腺激素β鍵，濾胞刺激素，與黃體化激素之濃度皆符合年齡標准。血清催乳素濃度則於高於，並持續至七個月進才回複正常。此高催乳素血症之成因未明，出生後七個月，男嬰之乳房肥大全部消退。乳房之超音掃描顯示女樣男乳變化。 足月新生兒幾全有乳房發育，而乳房之大小與妊娠期及出生體重成正比，引致 新生兒乳房發育之內分泌因素。新生期疃性之乳房發育假設乃乳房組織受經胎盤輸入之雌激素刺激所致。本文所述之病嬰乃暫時性高催乳素血症與新生期乳房發育合併出現之例子。至於新生兒之高催乳素黑穗病血症是否乳房發育之病因則有待證明。
