    Abstract

    Restrictive dermopathy is a rare, lethal genodermatosis, characterized by a thin, tightly adherent skin which causes a dysmorphic facies, arthrogryposis and respiratory insufficiency. The recorded cases to date show a remarkable phenotypic similarity. Thinning of the dermis and the arrangement of collagen in parallel bundles appear to be constant findings. We have found many dead and degenerating fibroblasts in the dermis on ultrastructural examination, and have demonstrated their poor growth in vitro. Studies of collagen from a skin sample showed a marked increase in mature cross-links, indicating a decrease in skin collagen turnover. These findings suggest a primary disorder of fibroblasts, and may explain the apparent arrest in growth and differentiation of the skin which appears to be important in the pathogenesis of this rare condition.
