Epidermal Inclusion Cysts following Dupuytren's Percutaneous Needle Fasciotomy: A Case Report.

Percutaneous needle fasciotomy (PNF) is a favorable approach to Dupuytren's contracture management, usually reserved for Tubiana stage 1-2, uncomplicated disease. It is growing in popularity globally. Epidermal inclusion cysts are benign, commonly encountered cavities usually found on acral skin, rarely glabrous skin, and often following trauma. We present a 43-year-old laborer with two incidentally found epidermal inclusion cysts in the open excision of painful, Tubiana 3 and 2 Dupuytren's recurrence of his middle and ring fingers. He had undergone PNF to same 4 years prior. One cyst had ruptured. Both seemed to have migrated distally over time from the initial PNF site with progression of the Dupuytren's disease. This may be the only case of multiple epidermal inclusion cysts post PNF for Dupuytren's disease in the literature. The authors discuss factors contributing to epidermal inclusion cyst formation, and postulate whether needle choice may impact the risk of their development as a complication of PNF.
