[Immunohistochemical and immunologic changes in aponeurosis in Dupuytren's disease]

Authors examined the aponeurosis of 23 patients with Dupuytren's contracture and of 5, formerly healthy persons, who died in consequence of accidents. It was found that the IgA and IgM content of the palmar aponeurosis is significantly elevated in Dupuytren's disease. The distribution of the immunglobulin containing cells and the fibronection localisation of the aponeurosis was also examined. On the basis of their examinations they think that the autoimmun mechanism may have a role in the development of Dupuytren's disease.
