Infantile Fibrosarcoma in Older Child at Right Lower Leg: A Case Report.

BACKGROUND Infantile fibrosarcoma (IFS) is a rare tumor. The highest prevalence is in the first 2 years of life. Cases typically manifest in the extremities, with rapid initial growth, are non-tender, and are a poorly delimited masses that vary in size or consistency and lack sensitivity.

Study epidemiology of risk fracture in osteoporosis based on frax score, and osta score, with risk of fall using Ontario score in elderly Indonesia.

Background: Osteoporosis is characterized by a low bone mass of bone tissue. If osteoporosis is not treated properly, it will increase the high risk of fracture. The common causes of fracture on osteoporosis condition due to falls.

Emergency Surgery in High Volume Osteosarcoma of Left Proximal Humerus Due to Vascular Compromise: A Case Report.

BACKGROUND Osteosarcoma is the most common type of malignant bone tumor arising from mesenchymal stem cell. When occurring on the proximal humerus, it is associated with poor outcomes; there are numerous neurovascular structures around proximal humerus. Unfortunately, the degree of vascular involvement in osteosarcoma is rarely evaluated and reported.

Free non-vascularized fibular graft reconstruction after resection of metacarpal unicameral bone cyst: A case report.

Unicameral bone cyst (UBC) or simple bone cyst (SBC) is a benign cystic lesion commonly found in the humerus and femur that is mainly encountered during childhood. The currently available treatments for UBC of the hand commonly involve curettage, bone grafting, partial resection with or without grafting, multiple drilling, fracture immobilization and observation alone, and steroid injection. We herein report a case treated with total resection of the cyst and non-vascularized fibular graft in a 9-year-old right-handed female patient.

Imatinib mesylate inhibits tumorigenicity of malignant fibrous histiocytoma cells in vivo.

Background: Malignant fibrous histiocytoma (MFH) is one of the most diffuse and aggressive tumors among soft tissue sarcomas in adults, but still poorly characterized from the molecular viewpoint. MFH cell proliferation is inhibited selectively by imatinib mesylate, a tyrosine kinase inhibitor. The expressions of platelet-derived growth factor receptors (PDGFRs) and c-Kit have been previously examined in MFH cell lines and the inhibitory effect of imatinib mesylate on the MFH cell proliferation was tested.
