Abstract

Common blue naevi usually occur on the skin however subungual blue naevi are extremely rare pigmented lesions of the nail. They need to be differentiated from pigmentations, chromogenic nail diseases, infections and most importantly melanoma. Herein, a 39-year-old female patient with subungual blue naevus who presented together with elkonyxis is presented with a brief review of cases from the literature.

普通型藍痣多發生在皮膚上，甲下藍痣則是極為罕見的甲色素性病變。此病須與其他情況區分，如外源性色素沉著、指甲病和最要緊的黑色素瘤。在此，我們報告一名三十九歲女性患者的甲下藍痣，其一併表現為鑽孔狀甲缺損；另簡要回顧文獻上的其他案例。
