Metastasis to the lymph nodes is relatively rare in malignant bone and soft-tissue tumors, and its risk factors remains unknown, except for tumors of the lymphogenous histotype, including rhabdomyosarcoma, epithelioid sarcoma, and clear cell sarcoma. The purpose of this study was to identify the risk factors for lymph node metastasis of malignant bone and soft-tissue tumors. We retrospectively ...

tissue-engineered gingival graft was used for regenerating facial gingiva around an implant at lower left first premolar area with insufficient attached gingiva. engineered gingival graft was produced by mixing 250 ml bovine skin collagen with 250 ml nutritional medium containing human gingival fibroblasts (2×105). 3 months post-surgery, there were gains in the attached gingiva compared to pre-...

Periarticular cyst and cystic soft tissue lesion around the knee are common. Synovial sarcoma is a rare and malignant soft tissue tumor accounting for approximately 5% of soft tissue sarcoma. A case is presented where a lesion adjacent to the joint line of the knee was diagnosed clinically and on imaging as a meniscal cyst. MRI signal was homogenous and no concomitant meniscal tears were seen. ...

BACKGROUND FUS1 is a tumor suppressor gene located on human chromosome 3p21.3. Frequent loss of FUS1 protein expression is associated with lung cancer development. This study examined FUS1 expression and its possible tumor-suppressive role in bone and soft tissue sarcomas. MATERIALS AND METHODS The expressions of FUS1 mRNA and FUS1 protein were assessed in sarcoma cell lines, sarcoma tissues,...

A case of a 36-yr-old woman with retroperitoneal synovial sarcoma is described. Her presenting symptom was epigastric pain that radiating to the back. On radiologic study, bulky retropancreatic soft tissue mass was detected which showed cystic and solid components. At operation, complete resection of the tumor was not possible because of the adhesion to the vena cava and the liver. During the f...

Hibemoma is a rare benign soft tissue tumor derived from brown fat.The tumor is also known as "fetal lipoma, lipoma of embryogenic fat and lipoma of immature adipose tissue. Hibemomas are slow-growing, painless soft tissue tumors which do not recur after surgical resection. Preferred locations are brown fat containing sites as thigh, interscapular region, shoulder, axilla, and mediastinum.The t...

lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. typically the tumor is asymptomatic unless bitten or become noticeable because of th...
