Abstract:
We describe the clinical presentation and pathological features of an infantile fibrosarcoma of the femur that occurred in a 3 1/2-month-old male infant. The tumor grew rapidly, reaching large size within a few months, finally requiring amputation. The tumor was poorly circumscribed, infiltrating the adjacent soft tissue extensively. Microscopically, it was a highly cellular tumor composed of immature-appearing spindle-shaped cells. Ultrastructural study revealed mesenchymal cells with fibroblastic and histiocytic differentiation.
Insights
This case report details an infantile fibrosarcoma in a 3-month-old infant. The aggressive femur tumor required amputation due to rapid growth and extensive infiltration.
Area of Science:
- Pediatric Oncology
- Skeletal Tumors
- Pediatric Pathology
Background:
- Infantile fibrosarcoma is a rare soft tissue tumor affecting infants.
- Femoral localization of this tumor is uncommon, presenting unique diagnostic and therapeutic challenges.
Observation:
- A rapidly growing, poorly circumscribed mass was observed in the femur of a 3 1/2-month-old male infant.
- The tumor extensively infiltrated adjacent soft tissues, necessitating surgical intervention.
Findings:
- Microscopic examination revealed a highly cellular tumor composed of immature spindle-shaped cells.
- Ultrastructural analysis indicated mesenchymal cells with both fibroblastic and histiocytic differentiation.
Implications:
- This case highlights the aggressive nature of infantile fibrosarcoma.
- Early diagnosis and aggressive management, including amputation in this case, are crucial for pediatric patients.
