Prediction of recurrence in the treatment of Dupuytren's disease: evaluation of a histologic classification.

Histologic staging of Dupuytren's lesions into three types is proposed: a proliferative type with high cellularity and mitosis, a fibrocellular type characterized by the presence of a reticulin network, and a fibrous type with few cells. Sixty-three patients (77 hands) who had selective fasciectomy as a primary procedure and whose histologic specimen was available were clinically reviewed for disease recurrence and extension. Twenty-two hands (29%) were free of disease; twenty-five (32%) were free from recurrence but showed an extension, and thirty (39%) had a recurrence. This histologic classification seems to have a prognostic value because the recurrence rate is higher in type I (70%) and lower in type III (18%). The risk of extension did not correlate with the histologic type.
