Summary
Desmoplastic fibroblastoma, a rare benign tumor, can unusually present as a large, invasive mass. Despite aggressive features, complete surgical removal ensures a favorable long-term outcome without recurrence.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Desmoplastic fibroblastoma is a rare, benign tumor typically presenting as a small, indolent lesion with a favorable prognosis.
- Characterized by fibroblastic cells in a collagenous background, bone invasion is exceptionally uncommon.
Observation:
- This report details an atypical case of desmoplastic fibroblastoma presenting as a massive 23-cm tumor.
- The tumor exhibited significant infiltration and destruction of the scapula, a highly unusual feature for this diagnosis.
Findings:
- The large, invasive tumor was unresponsive to chemotherapy, necessitating limb-sparing surgery.
- En bloc resection, complete scapulectomy, and osteoarticular allograft replacement were performed.
Implications:
- This case highlights that desmoplastic fibroblastoma can attain enormous size and exhibit invasive properties.
- Despite aggressive presentation, successful surgical excision leads to a disease-free status, underscoring the tumor's benign nature.
