The incidence of thyroid cancer has increased markedly in recent decades, but has been stable in terms of mortality rates. For the most part, these cancers are treated with surgery, which may or may not be followed by radioactive iodine depending on the tumor subtype. Still, many of these cancers will recur and may be treated with radioactive iodine or another surgery. It is unclear what treatment is best for cases of locally advanced or metastatic thyroid cancer that are refractory to radioactive iodine. Chemotherapy has a very low response rate. However, in the past few years, several systemic therapies, primarily targeted, have emerged to improve the overall survival of these patients. Alternative treatments are also of interest, namely peptide receptor radionuclide therapy or immunotherapy.

INTRODUCTION: As healthcare expenses are escalating in many countries, the sector faces a new challenge of becoming more cost efficient. There is an urgent need for more accurate data on the costs of healthcare procedures.

We describe a 43-year-old woman who presented a sudden onset of fever and migratory arthralgias. Physical examination revealed tender, well-demarcated erythematous papules and plaques, consistent with a Sweet syndrome. After developing systemic symptoms with hepatomegaly, a liver biopsy and FDG PET imaging demonstrated the presence of an aggressive and extended non-Hodgkin T-cell lymphoma. This case highlights the usefulness of FDG PET imaging for the screening of this paraneoplastic syndrome.
