Summary
Extraskeletal osteosarcoma, a rare soft tissue tumor, was successfully treated in a forearm case. Surgical resection and chemotherapy led to an eighteen-month recurrence-free and metastasis-free outcome.
Area of Science:
- Orthopedic Oncology
- Soft Tissue Pathology
Background:
- Extraskeletal osteosarcoma is an exceptionally rare malignant soft tissue neoplasm.
- This tumor typically presents as a rapidly growing mass, often mistaken for other soft tissue lesions.
Observation:
- A 62-year-old female presented with a six-month history of a right forearm tumor.
- Physical examination revealed a large (10 x 12 cm) mass with central ulceration.
- Magnetic Resonance Imaging (MRI) showed a heterogeneous mass distinct from the underlying bone and periosteum.
Findings:
- Pathological examination of the surgically resected specimen confirmed extraskeletal osteosarcoma.
- The patient received adjuvant chemotherapy post-surgery.
- The patient remained disease-free with no local recurrence or distant metastasis at an eighteen-month follow-up.
Implications:
- This case highlights the importance of considering rare soft tissue tumors in differential diagnoses.
- Successful management involved a multidisciplinary approach combining surgery and chemotherapy.
- Early diagnosis and complete resection are crucial for favorable prognoses in extraskeletal osteosarcoma.
