Fibrous long-spacing collagen in the perineurium of human sural nerve.
Banded structures are reported to occur in the thickened perineurium of four normal human sural nerves (material from autopsy cases: one female and three males between 64 and 90 years old; three died of secondary complications of atherosclerosis, one died from cerebral contusion after an accident). The structures were found adjacent to typical perineurial cells as well as to fibroblast-like cells, and in association with an increased amount of basement membrane material. The pathologic significance of these structures is briefly discussed.
