Polytef Granuloma Clinically Simulating Carcinoma of the Thyroid

Histologic Evaluation of Teflon Granulomas of Human Vocal Cords:A Light and Electron Microscopic Study

Clinical Experience With Gore‐Tex for Vocal Fold Medialization

“…Dedo 4 studied Teflon explanted from patients who developed complications after injection and confirmed both the giant‐cell process around Teflon particles and the tendancy to fibrotic encapsulation. Palpable tumors have been reported in some cases 28 . Taken together, these findings suggest that granulomatous reaction after injection of Teflon is underestimated (2% to 3%) 5 .…”

“…In 1973 and 1975, Goff [11] and Walsh and Castelli [ 12] reported the same findings in patients who had died between 4 days and 18 months after a vocal cord injection for paralysis due to cancer in 2 cases and idiopathology in 1. In 1 case, a complete autopsy was performed in addition to the larynx study.…”
