The aim of our study was to assess the distribution of phosphorylated a-synuclein (p-syn) deposits in a patient affected by early stage Parkinson disease and orthostatic hypotension through a longitudinal skin biopsy study. We found widespread p-syn spatial diffusion from deep autonomic dermis nerve bundles to autonomic terminals, suggesting a centrifugal spread of p-syn from ganglia to the innervation target structures. Furthermore, the case suggests the possibility of discriminating synucleinopathies at an early stage of disease by means of skin biopsy. If confirmed, these data support skin biopsy as a useful and promising tool for the diagnosis, longitudinal evaluation, and pathological understanding of Parkinson disease.

Abstract
The aim of our study was to assess the distribution of phosphorylated a-synuclein (p-syn) deposits in a patient affected by early stage Parkinson disease and orthostatic hypotension through a longitudinal skin biopsy study. We found widespread p-syn spatial diffusion from deep autonomic dermis nerve bundles to autonomic terminals, suggesting a centrifugal spread of p-syn from ganglia to the innervation target structures. Furthermore, the case suggests the possibility of discriminating synucleinopathies at an early stage of disease by means of skin biopsy. If confirmed, these data support skin biopsy as a useful and promising tool for the diagnosis, longitudinal evaluation, and pathological understanding of Parkinson disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
