The modified Rodnan skin score is an accurate reflection of skin biopsy thickness in systemic sclerosis.

Abstract

Total and forearm skin score correlates well with both wet and dry forearm skin biopsy weight from forearm biopsies, indicating that skin score reflects the underlying pathology of SSc. Further, the percentage of dry to wet weight is similar for lSSc and dSSc, supporting the usefulness of skin score in differentiating SSc disease subtypes.
