Clinical and Dermoscopic Features of Subungual Hemorrhage: A Retrospective Study of 420 Cases
By Wu X, Lin Z, Shen X and 11 others.
Abstract
Background
Subungual hemorrhage (SH) may be difficult to distinguish from nail unit melanoma, onychomycosis, and other nail disorders. Dermoscopy enables non-invasive visualization of subtle subungual structures and provides useful information for differential diagnosis. This study aimed to analyze the clinical and dermoscopic features of SH and explore their associations with lesion location, disease course, and nail involvement.
Materials and methods
Clinical and dermoscopic data of 420 patients diagnosed with SH between December 2018 and March 2024 were retrospectively collected from two tertiary hospitals in China.
