title: PET/CT imaging of squamoid eccrine ductal carcinoma.
abstract: Squamoid eccrine ductal carcinoma is an extremely uncommon type of eccrine carcinoma (EC). An important distinguishing feature of EC is potential for metastasis. Eccrine carcinoma has been reported to metastasize in up to 50% of cases. Despite tumor aggressivity, no recommendations for staging exist. We present the case of a 91-year-old woman with a lesion involving the left index finger confirmed to be squamoid eccrine ductal carcinoma by dermatopathologic evaluation. 18F-FDG PET/CT images revealed widespread multifocal FDG-avid metastatic disease. Although rare, staging of EC with 18F-FDG PET/CT imaging of the entire body is indicated.
