Painless Growing Swelling on the Palm of a 4-year-old Boy: Malignant Peripheral Nerve Sheath Tumor.

In this study, we present a 4-year-old male patient with a slowly growing painless mass in the palm of his left hand for 2 years. Although musculoskeletal tumors are rare, hand localized tumors are even rarer in pediatric patients. The fact that very few (less than one in ten) tumors are malignant and there are dozens of subtypes, each with different treatment management, shows the importance of the management of these lesions.

First case of medullary osteogenic sarcoma of the pelvis: 12-year follow-up of reconstruction with hemipelvis allograft after resection.

Outcomes of Planned Marginal and Wide Resection of Sarcomas Associated with Major Vascular Structures in Extremities.

Bone and soft tissue sarcomas of lower and upper extremities may sometimes be in close contact with neurovascular structures. In such cases, it is controversial that whether en bloc resection and vascular reconstruction to reach wider surgical margins or planned marginal resection with the help of adjuvant therapies should be preferred. This study aimed to determine surgical and oncological outcomes of planned marginal and wide resection of extremity sarcomas that are associated with major vascular structures in the extremities.
