Improving precision of resection by pre-surgery inspections with contrast-enhanced ultrasound for dermatofibrosarcoma protuberans.Dermatofibrosarcoma protuberans (DFSP) is a relatively uncommon malignant soft tissue tumor.  In order to minimize the range of resection area, the contrast-enhanced ultrasound (CEUS) was used to precisely identify the tumor affected area before the surgery treatment.

In order to minimize the range of resection area, the contrast-enhanced ultrasound (CEUS) was used to precisely identify the tumor affected area before the surgery treatment.  The result shows that CEUS depicted clear structure of the tumor, which successfully helped surgeons to reduce the resection range from 3 cm to 2 cm in diameter.  Pre-surgery CEUS inspection of DFSP could be an effective and economical method to minimize the patient's hurts in the surgical treatment of DFSP.
