On the basis of clinical features and histological findings, cutaneous manifestations of linear melorheostotic scleroderma are apparently derived from a localized proliferative disorder and are not secondary to bone changes. If the hypertrichosis has the same origin as the osteocutaneous changes, melorheostosis may represent a congenital disorder with both ectodermic and mesodermic components.
