Computed tomography (CT) of a 68-year-old man showed multiple small nodules in the bilateral lungs (maximum 14 mm in the left upper lobe). CT-guided biopsy of left upper lobe lesion showed no tumor or granuloma. Fluorodeoxyglucose (FDG) PET/CT showed multiple nodules with background-to-mild FDG-avid activity, and an incidental left scrotal skin lesion with intensely increased accumulation of 18F-FDG (SUVmax, 11.7), suspected malignant. After urologist consultation, local dermatological findings suggested a huge wart. Excision was done, and pathology concluded nodular papillary fibroepithelial polyp with acute and chronic inflammation.
