Abstract

BACKGROUND:

Progressive systemic sclerosis (PSS) is a chronic connective tissue inflammatory disease which commonly attacks the skin and the visceral organs, but rarely the peripheral nervous system.

OBJECTIVE:

The aim of this study was to investigate PSS accompanied by peripheral neuropathy clinically, electrophysiologically and pathologically from a sural nerve biopsy.

METHODS:

Two women suffering from PSS but without any other collagen disease were studied. Both patients developed peripheral neuropathy with multiple mononeuropathy of the limbs, and in one woman, in the trunk as well.

RESULTS:

A biopsy of the sural nerve revealed axonal and myelin segmental degeneration, loss of large myelinated fibers and an increase of collagen fibers, but there was no evidence of vasculitis. An electron microscopic examination revealed degenerated axons, disrupted myelin sheaths and multilayered basal lamina in the capillaries.

CONCLUSION:

Mononeuropathy in PSS suggests that ischemic neuropathy may be related to the immune-mediated vasculopathy.
