The spots are named after the physician Thomas Brushfield, who first described them in his 1924 M.D. thesis.〔Wallis, Hugh R.E. ("The Significance of Brushfield's Spots in the Diagnosis of Mongolism in Infancy" ), ''Archives of Disease in Childhood'', 1951 December; 26 (130): 495-500. Retrieved on 21 March 2009.〕 These spots are normal in children (Kunkmann-Wolffian bodies), but are also a feature of the chromosomal disorder Down syndrome. They occur in 35–78% of newborn infants with Down syndrome. They are much more likely to occur in children with Down syndrome of the Caucasian race than children of Asian heritage with Down's Syndrome. They are focal areas of stromal hyperplasia, surrounded by relative hypoplasia, and are more common in patients with lightly pigmented irises. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brushfield spots」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
