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

Background: Skin tightness is a hallmark of systemic sclerosis (SSc), and the fingers are an affected body part, so much so that fingerprints can be significantly affected among those with extensive skin tightness of the finger.

Objective: We aimed to compare the difference between the current and past (pre-disease onset) fingerprints of SSc patients.

Methods: We conducted a cross-sectional study among adult SSc patients who attended the Scleroderma Clinic, Khon Kaen University, between October 2019, and September 2020.
