ABSTRACTIntroduction: A description of a male patient with prior treatment for a right lung adenocarcinoma and a close follow-up for a right thyroid lobe 7 mm papillary cancer, who developed massive right neck metastasis. Objective: To describe the diagnostic dilemma to confirm or rule out the origin of the multiple neck metastasis to avoid unnecessary treatments. Methods: The biopsies from the lung, thyroid and neck tissues were reviewed and examined with immunohistochemistry. Results: The neck metastasis originated from an adenocarcinoma of the lung with papillary features. Conclusions: Unnecessary radioactive iodine treatments were avoided, thanks to the tumor markers.
