title: A false-positive FDG uptake in Teflon granuloma: a case report.
abstract: Positron emmision tomography (PET) is successfully used to monitor malignancies. Unfortunately it is not tumor specific. We present a case with history of rectum cancer and lentigo maligna who underwent PET-CT which revealed an increased uptake in the larynx. What was first considered as a third primary turned out to be a Teflon granuloma.
