Multiple palmar epidermoid cysts: fourth reported case

Palmar epidermoid inclusion cyst mimicking Dupuytren's contracture

“…HPV infection has been shown to be associated with palmar epidermoid inclusion cysts, although it is not commonly encountered diseases in hand surgery [5][6][7]. In our case, HPV infection was screened but not detected postoperatively.…”

“…Epidermoid inclusion cysts occur via penetration and implantation of epidermal structures into the dermis [7]. Another theory for the development of these cysts is the cystic ectasia of the hair follicles.…”

“…However, this theory does not explain the existence of palmar epidermoid inclusion cysts in a hairless area. Recent studies have shown that the cyst walls are adjacent to the eccrine ducts and suggesting that they may be originated from these ducts [4,7]. Since the palm is an exposed area for traumas, an old trauma or a foreign body penetration may cause epidermoid inclusion cysts.…”
