Clinical Image

An 87-year-old Japanese man presented with severe chest pain, lower back pain, anorexia, and malaise. He had a surgical history of Extramammary Paget’s Disease (EMPD) of the penis and scrotum (Figure A). Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-PET/CT) revealed multiple bone lesions with FDG uptake, including the vertebrae, bilateral ribs, scapulae, the sternum, the pelvis, and the right femur, the so called “super scan” (Figure B). The super scan phenomenon is characterized by intense activity in the bones and diminished activity in the soft tissue and in renal parenchyma in bone scintigraphy; it is commonly observed in prostatic or breast cancer [1]. In this case, super scan on FDG-PET/CT was caused by EMPD, a cutaneous malignancy of apocrine sweat gland origin. EMPD commonly metastasizes to the regional lymph nodes, the liver, the lungs, and the bones, and the diagnosis of bone metastases was made with the help of FDG-PET/CT [2].
