title: FDG PET/CT in malignant eccrine porocarcinoma arising in a pre-existing poroma.
abstract: In a 61-year-old man with known poroma of right lower abdomen, malignant transformation to porocarcinoma was suspected and confirmed by biopsy. PET/CT was requested for tumor staging, which revealed high FDG uptake in the known skin nodules located in the right side of abdominal and chest wall and identified further some adenopathy in the right axillary. All nodules and axillary lymph nodes were removed, and diagnosis of eccrine porocarcinoma was confirmed. The primary tumor and secondary lesions of porocarcinoma show a high glucose metabolism; thus, PET/CT could be useful for staging, follow-up, and detection of recurrence of patients with eccrine porocarcinoma.
