An immunohistochemical study was performed on nodules excised from the palmar fascia of patients with Dupuytren’s contracture. In cellular nodules, antibodies to actin (used as a marker for myofibroblasts), desmin, vimentin, Mac 387 (a macrophage marker) and leucocyte common antigen were used. A correlation was demonstrated between the numbers of macrophages and the presence of myofibroblasts. The presence of myofibroblasts is generally considered to indicate the active stage of the disease. Inflammatory cells other than macrophages were largely absent from the nodules, although lymphocytes were frequent in the tissue around the nodules. Microvascular changes were prominent in the nodules and pericyte proliferation was observed around occluded capillaries. Release of growth factors from macrophages may be important in Dupuytren’s contracture, as is the case in other fibrotic diseases. The possible role of macrophages in the aetiology of Dupuytren’s disease is discussed.
