Abstract
The aim of this paper was to examine participation of the epidermal growth factor receptor (EGF-R) signal pathway in the pathogenesis of Dupuytren’s disease. The study showed changes in the ratio of membrane EGF-R to its intracellular level during the different clinical stages of Dupuytren’s contracture progression. Our observations of a high ratio of surface to intracellular EGF-R in the palmar aponeurosis of patients with second degree of Dupuytren’s disease (Iselin’s classification), which was significantly higher than this ratio in control palmar fascia (P = 0.022), would suggest that EGF-R has a role in the involutional phase of the disease.
