Soft tissue sarcomas account for 1% of solid tumors in adults and 15% in childhood. They are often located in the extremities. There are many subtypes, and they may present with very different clinical presentations. While some patients may present in the early period with localized pain, swelling and tenderness, some deeply located soft tissue sarcomas present with symptoms after they reach a large size. Prognostic factors of soft tissue sarcomas are; the patient`s age, location, histological type, size, stage of the tumor, proximity to the surgical margin of the resection and whether it is metastatic at first admission. Current evidence about the prognosis of bone invasion at diagnosis is low. Studies have shown that bone invasion can reduce survival rates, especially in large and advanced histological-stage sarcomas. Clinical and radiological examination is crucial in soft tissue sarcomas with bone involvement. Roentgenogram, magnetic resonance imaging, and computed tomography help demonstrate bone invasion. While amputation was used in the past, limb-sparing surgery has become preferable in recent years. It should be remembered that while the soft tissue sarcoma is resected with wide margins, resection and reconstruction of the involved bone segment may be required in these patients.
