Abstract

Melanonychia striata represents a diagnostic dilemma for dermatologists. The use of dermoscopy to assess the nail has advantages over clinical examination. However, when compared to skin lesions, it gives fewer details. We describe two cases of melanonychia striata submitted to dermoscopic examination of the nail bed and matrix. This is a new procedure that enables observing dermoscopic characteristics that are not visualized in the nail plate, thus, providing additional information.

摘要

甲黑线对皮肤科医生来说是一个诊断难题。使用皮肤镜评估指甲比临床检查更具优势。然而，与皮肤病变相比，它提供的细节较少。我们描述了两例接受甲床和甲母质皮肤镜检查的甲黑线病例。这是一种新的检查方法，能够观察到在甲板中无法看到的皮肤镜特征，从而提供额外的信息。
