An unusual and aggressive case of Dermatofibrosarcoma Protuberans (DFSP) with fatal disease course is presented. In the present case, the high grade 18F-FDG uptake in the DFSP lesions was predictive of an aggressive disease course in this otherwise indolent behaving entity. The aggressive clinical course was unabated by tyrosine kinase inhibitor imatinib mesylate and the patient showed poor response to this therapy.
