Summary
Proliferative fasciitis, a fibrous lesion, exhibits spontaneous evolution and involution. This case study highlights its rapid decrease in size and pain, suggesting conservative management may be suitable.
Area of Science:
- Pathology
- Radiology
- Oncology
Background:
- Reactive fibrous lesions typically undergo evolution and involution, a characteristic not widely recognized in current literature.
- Proliferative fasciitis is a rare pseudotumorous fibrous proliferation that can mimic other soft tissue masses.
Observation:
- A 35-year-old woman presented with a tender forearm soft tissue mass that rapidly grew over two weeks.
- Initial MR imaging showed a non-specific soft tissue mass, and needle biopsy confirmed proliferative fasciitis.
Findings:
- The soft tissue mass significantly decreased in size, and associated pain resolved within two weeks post-biopsy.
- Follow-up MR imaging revealed only minimal residual reactive changes along the muscle fascia.
Implications:
- The dynamic changes observed in this case suggest that proliferative fasciitis may undergo spontaneous involution.
- Conservative management could be a viable treatment option for proliferative fasciitis, potentially avoiding surgical intervention.
- Further research into the natural history and optimal treatment strategies for proliferative fasciitis is warranted.
