The aim of the article is to emphasize the importance of including a second primary cancer as a differential diagnosis among patients at risk. Case outline We present a case of a patient diagnosed with two separate malignancies almost two decades after the treatment of HL. Conclusion In patients previously treated for HL, a biopsy of lesions that show high 18F-FDG uptake should be advised, particularly if the location of the lesion is unusual for the primary diagnosis. © 2025, Serbia Medical Society.
