貝克氏黑變症是各種族皆常見的皮膚問題,有極少數的貝克氏黑變症會合併有組織的發育異常,大部份的病歷報告都是發育不足(hypoplasia),我們在此報告一個合併同側下肢肥大及漏斗胸之貝克氏黑變症病歷。回顧文獻,這是第二例合併肢體肥大的病例,也是第一例合併漏斗胸的病例。
Becker’s melanosis is a fairly common disorder found in all races. Rarely, Becker’s melanosis may be associated with hypoplasia or hyperplasia of underlying structures. With the exception of one patient with foot enlargement, most reported associated features have been hypoplastic. We report one case with extensive Becker’s melanosis accompanied by ipsilateral lower limb hyperplasia and pectus excavatum. In the literature, this is the second case associated with hyperplasia of underlying structure and the first case associated with pectus excavatum.
