Xeroderma pigmentosum is a genodermatosis with neurological manifestations
in approximately 18p. 100 of cases. Polymorphous and variably associated si
gns are observed, progressing with the clinical course. The etiology of the
neurological breach remains unknown. We report two siblings who had xerode
rma pigmentosum with intellectual deficiency, a pyramidal, cerebellar and c
ordonal syndrome, ophthalmoplegia, and axonal peripheral neuropathy. We dis
cuss the epidemiological, clinical and electrophysiological aspects of the
neurological breach in xeroderma pigmentosum.
