Radiologic-Pathologic Correlations of Fibrosarcomatous Dermatofibrosarcoma Protuberans With Various Histological Features on Enhanced MRI and PET/MRI

摘要

Dermatofibrosarcoma protuberans (DFSP) is a cutaneous tumor of intermediate-grade malignant potential, and it rarely shows dedifferentiation to high-grade fibrosarcoma, which is called "fibrosarcomatous DFSP." We present the enhanced MRI and PET/MRI findings and our comparison with pathological findings in a case of fibrosarcomatous DFSP with various histological features.
