Sparing phenomenon in salt and pepper pigmentation of systemic sclerosis: an unusual observation.

In systemic sclerosis, vitiligo-like depigmentation of salt and pepper pigmentation usually spares the perifollicular areas. Pigmentation is also known to be preserved over the superficial veins. We describe a case series of salt and pepper pigmentation with some unusual features. We would like to emphasize that in about 40% of patients of the present series, the salt and pepper pigmentation spared the skin creases and folds, which appears to be a hitherto unreported finding.
