摘要

背景:角膜下血肿(SH)的诊断具有挑战性,因为其临床表现可能与黑色素细胞病变相似。很少有研究探讨了角膜下血肿的皮肤镜特征,但需要进行更详细的大规模研究,以克服将角膜下血肿与口角黑色素瘤相鉴别的诊断难题:描述SH的皮肤镜特征:方法:我们评估了釜山大学医院(釜山和梁山)43名患者的50个SH皮损的临床和皮肤镜特征:在颜色分析中,86%的病例表现为瘀斑色征;7 例病例为单一颜色(红色至紫色:2 例;黑色:1 例;棕色:4 例)。在 60%、0% 和 72% 的病变中分别观察到 SH、尖锐痣和尖锐黑色素瘤相关模式的典型皮肤镜特征。与血瘤相关的图案为均匀的红黑色,伴有或不伴有卫星球(32%),以及脊上的卵石(28%)。口腔黑色素瘤相关形态表现为平行脊形态(PRP)(52%)、不规则点状和球状(50%)、多色(34%)、不对称(24%)、不规则斑点(10%)和溃疡(10%)。没有病例出现蓝白色纱幔、回归结构、非典型血管形态或不规则纤维形态。大多数病例的瘀斑颜色征呈阳性,并伴有尖锐黑色素瘤相关形态(88.9%)。

Dermoscopic Features of Subcorneal Hematoma on the Palms and Soles: Differences from Acral Melanoma.

Background: The diagnosis of subcorneal hematoma (SH) can be challenging because the clinical presentation of SH can resemble melanocytic lesions. Few studies have examined the characteristic dermoscopic features of SH, but a more detailed large-scale study is needed to overcome the diagnostic challenge of differentiating it from acral melanoma.

Objectives: To describe the dermoscopic features of SH.

Methods: We evaluated the clinical and dermoscopic features of 50 SH lesions from 43 patients at the Pusan National University Hospitals (Busan and Yangsan).

Results: In the color analysis, 86% of cases showed the bruise color sign; 7 cases had a single color (red to purple: 2; black: 1; brown: 4). Typical dermoscopic features of SH, acral nevi, and acral melanoma-associated patterns were observed in 60%, 0%, and 72% of lesions, respectively. Hematoma-associated patterns were homogenously red-to-black with or without satellite globules (32%) and pebbles on the ridges (28%). Acral melanoma-associated patterns showed a parallel ridge pattern (PRP) (52%), irregular dots and globules (50%), polychromia (34%), asymmetry (24%), irregular blotches (10%), and ulcers (10%). No case showed blue-white veils, regression structures, atypical vascular patterns, or irregular fibrillar patterns. The bruise color sign was positive in most cases, with acral melanoma-associated patterns (88.9%).
