Abstract

To determine whether skin biopsy is practically useful in the premortem diagnosis for Parkinson's disease (PD), we examined Lewy pathology in the skin of the chest wall and leg, obtained from 6-mm punch biopsies, using phosphorylated α-synuclein antibody in 20 patients with clinically diagnosed PD. Abnormal accumulation of α-synuclein was found in the chest skin of two (10%) of 20 patients, but not in the leg. Although skin biopsy combined with a conventional immunohistochemistry for α-synuclein is not sufficient as a diagnostic tool, we could firstly demonstrate Lewy pathology in premortem tissue. The skin remains to be a promising tissue to be examined for the premortem diagnosis of PD.

    It is easy to perform and can be repeated over time with minimal invasiveness. It is an interesting tool for stratification studies (Korecka et al., 2019; Carling et al., 2020), and also for detecting established biomarkers (Miki et al., 2010; Donadio et al., 2014; Miglis and Muppidi, 2020) and identifying new ones, to improve PD diagnosis, patient-targeted therapy and patient follow up. Some skin biopsy studies focused on detecting phosphorylated αSyn deposits in nerve fibres in the skin.
