title: Imaging Features of Breast Dermatofibrosarcoma Protuberans in Various Modalities Including FDG-PET CT.
abstract: Dermatofibrosarcoma protuberans is an uncommon malignant mesenchymal tumor of the dermis, which most commonly appears on the body and extremities. A preoperative diagnosis of dermatofibrosarcoma protuberans is extremely difficult, because it is a very rare entity and its appearance is often similar to that of benign breast lesion. Here, we presented a case of breast dermatofibrosarcoma protuberans with associated radiological mammography, ultrasound, magnetic resonance imaging and fludeoxyglucose-positron emission tomography computerized tomography (FDG-PET CT) features. To our knowledge, our case is the first report of PET-CT findings of breast dermatofibrosarcoma protuberans. Furthermore, we reviewed characteristic radiologic features of this rare entity, which are helpful for differentiating it from other primary benign breast lesions.
