Magnetic resonance (MR) imaging helps identify the extent and location of dermatofibrosarcoma protuberans. Understanding its varied appearances, including deep or ill-defined tumors, aids diagnosis.

Area of Science:

  • Radiology
  • Oncology
  • Dermatopathology

Background:

  • Dermatofibrosatcoma protuberans (DFSP) is a rare, locally aggressive skin cancer.
  • Accurate staging and characterization are crucial for effective treatment planning.

Purpose of the Study:

  • To delineate the magnetic resonance (MR) imaging characteristics of DFSP.
  • To correlate imaging findings with histological confirmation in a series of cases.

Main Methods:

  • Retrospective review of 10 histologically confirmed DFSP cases.
  • Analysis of MR imaging features, including location, size, margins, and enhancement patterns.

Main Results:

  • DFSP demonstrated variable MR imaging appearances.

  • Most tumors were superficial and well-defined, but deep-seated and ill-defined lesions were also observed.
  • MR imaging accurately depicted tumor extent and relationship to adjacent structures.

    • Conclusions:

    • MR imaging is a valuable tool for assessing the extent and location of DFSP.
    • Awareness of diverse MR imaging presentations can improve diagnostic accuracy, especially in atypical cases.
    • This knowledge aids in differentiating DFSP from other soft tissue tumors.
