Dermoid Inclusion Cyst Following Percutaneous Needle Fasciotomy: A Novel Complication.

We present the case of a fit and well 62-year-old male with Dupuytren's disease in the right hand who underwent percutaneous needle fasciotomy (PNF) for a moderate flexion contracture of the right little finger. 18 months later he developed a pain-free soft tissue swelling at the distal previous needling site. A fasciectomy procedure identified a cyst within the pre-tendinous cord, which was confirmed as a dermoid inclusion cyst on histological analysis. Dermoid inclusion cysts may occur in the hands at the site of penetrating trauma but we are unaware of any report of an inclusion cyst at the site of PNF surgery. We present this unique case of a dermoid inclusion cyst following percutaneous needle fasciotomy as a novel complication.
