Аннотация
The sural nerves of 2 siblings, 7 and 6 years of age with Group A xeroderma pigmentosum, were biopsied. The densities of myelinated fibers, 5,808/mm2 and 5,163/mm2, respectively, were strikingly decreased in comparison to control data. Both large and small myelinated fibers were reduced. Electron microscopy demonstrated many collagen fibers in the endoneurium and some collagen pockets. The loss of myelinated fibers was less severe than in previously reported patients. This discrepancy may be due to age differences at biopsy; our patients were biopsied at the ages of 7 and 6 years, while those patients reported previously were 10 years of age or older. The incidence of neurologic manifestations in xeroderma pigmentosum may increase after 6 years of age.
