Severe systemic delayed dermatitis in a patient with nickel–titanium sterilization microinserts perforating the uterus

Abstract

We report a case of severe systemic delayed dermatitis in a patient with nickel–titanium sterilization microinserts placement complicated by uterine perforation and polyethylene terephthalate (PET) exposure. We hypothesize that delayed dermatitis may be caused by the exposure of PET fibers in this patient with underlying autoimmune disorder. Further research on the use of PET and the potential of systemic dermatologic reactions when exposure occurs is needed, especially when considering the inclusion of PET in future implant device development.
