Summary
Dermatofibrosarcoma protuberans (DFSP), a rare skin cancer, can metastasize to the central nervous system (CNS), a previously unreported occurrence. This case highlights the aggressive potential of DFSP and its unusual metastatic patterns.
Area of Science:
- Oncology
- Pathology
- Genetics
Background:
- Dermatofibrosarcoma protuberans (DFSP) is an intermediate-grade soft tissue sarcoma.
- DFSP typically presents as a locally aggressive cutaneous tumor with a risk of recurrence and distant metastasis.
Observation:
- A case of a 43-year-old Filipino male with DFSP who developed local recurrence, pulmonary metastasis, and sequential central nervous system (CNS) metastases is presented.
- The metastatic lesions exhibited fibrosarcomatous change, high cellularity, high mitotic rate, loss of CD34 expression, and aneuploidy.
Findings:
- This report documents the first known instance of DFSP metastasizing to the CNS.
- Complex karyotypic aberrations were identified in the CNS metastasis, not previously associated with DFSP.
- The intracranial metastasis's dural-based location and microscopic features mimicked anaplastic syncytial meningioma.
Implications:
- The findings expand the known metastatic potential of DFSP.
- This case underscores the importance of considering DFSP in the differential diagnosis of CNS tumors, especially in patients with a history of DFSP.
- Further research into the genetic underpinnings of DFSP metastasis is warranted.
