Computed tomography (CT) can identify dermatofibrosarcoma protuberans (DFSP) and its location. Marginal enhancement with central low density on CT scans may indicate a poorer prognosis for this skin cancer.

Area of Science:

  • Radiology
  • Oncology
  • Dermatopathology

Background:

  • Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive skin cancer.
  • Accurate imaging is crucial for diagnosis and treatment planning.

Purpose of the Study:

  • To characterize the computed tomography (CT) findings of dermatofibrosarcoma protuberans (DFSP).
  • To correlate CT features with pathological findings and prognosis.

Main Methods:

  • Retrospective review of CT scans and corresponding pathologic specimens from 6 patients with DFSP.
  • Analysis of tumor location, size, and enhancement patterns on postcontrast CT.

Main Results:

  • CT effectively delineated DFSP tumors in the dermis and subcutaneous tissue.

  • Marginal enhancement with central low density was observed in 3 tumors, corresponding to fibrosarcomatous changes and necrosis.
  • Homogeneous enhancement was seen in tumors without sarcomatous changes.

    • Conclusions:

    • CT is valuable for detecting and precisely localizing DFSP.
    • Marginal enhancement with central low density on CT may suggest a less favorable prognosis.
