title: Pseudotumor formation in polytetrafluoroethylene-dialysis fistulae.
abstract: We report two patients with formation of pseudotumors along a polytetrafluoroethylene (PTFE) graft used for dialysis access in chronic fistulae. We postulate a relationship with seroma formation, a known complication of PTFE vascular grafts used for dialysis purposes, possibly through lipolysis of the surrounding fat by a protein-rich exudate.
