Fingerprint comparison between before disease onset and after systemic sclerosis diagnosis: a monocentric cross-sectional study.

Fingerprints were affected by fingertip lesions and finger joint contractures; notwithstanding, the prints remained usable for personal identification. Key Points • Skin involvement in systemic sclerosis (SSc) affects the prints, particularly at the fingertip. • Despite disease onset, the fingerprints of SSc patients do not change significantly. • Fingerprints are inadequate for personal identification among SSc patients with hand deformities due to poor quality or difficulty acquiring them.
