[The diagnostic importance of research on the lysyl oxidase activity in children with circumscribed scleroderma]

Blood serum lysyl oxidase activity considerably varies, these variations correlating with the skin process dissemination, in children suffering from focal scleroderma. This enzyme was undetectable in normal subjects and patients with dermatoses whose clinical symptoms are similar to those of focal scleroderma. Blood serum lysyl oxidase activity elevation is a specific sign, characteristic of patients with focal scleroderma; it therefore may be used for the laboratory diagnosis of this dermatosis, assessment of its dissemination and severity.
