..The aberrant overexpression of granulocyte colony-stimulating factor clearly represented a paraneoplastic phenomenon of the neoplastic cells...

..Intra-articular lipoma should be considered in the differential diagnosis of intra-articular masses in adolescents...

..Intra-articular lipoma should be considered in the differential diagnosis of intra-articular masses in adolescents...

..In the present cases, surgical excision of the tumors resulted in immediate and complete relief of chronic heel pain. Surgeons should consider neurilemmoma as a cause of persistent chronic heel pain despite the rarity of the disease...

..These characteristic findings on MR imaging are considered to facilitate establishing the radiologic diagnosis...

..The KTHOS cell line is a novel human osteosarcoma cell line that releases SCF and expresses KIT. This cell line can be used for studies to explore the mechanisms for oncogenesis of human osteosarcomas...

..Little information is available on the expression of stem cell factor (SCF) and its receptor c-kit in soft tissue tumors of a fibrohistiocytic origin, including malignant fibrous histiocytoma (MFH)...

..The cytologic features are indistinguishable from those of giant cell tumors of bone and brown tumors of hyperparathyroidism...

..Although periosteal osteoblastoma is rare, this tumor should be included in the differential diagnosis of surface-type bone tumors...

..The cells had elongated, oval, or partially bizarre-shaped nuclei with a coarse chromatin pattern and prominent nucleoli. The scrape smears contained large fragments of matrix material consistent with osteoid...

..The aims of the present study were to investigate the expression of TGF-beta isoforms and their receptors in human MFH specimens...

..Little information, however, is currently available on the amphiregulin and EGF receptor (EGF-R) expression in mesenchymal malignancies of a fibrohistiocytic origin including malignant fibrous histiocytoma (MFH)...

..Careful evaluation of the background of the smears coupled with full knowledge of the clinical and radiological findings, including magnetic resonance imaging, is required to establish the correct diagnosis...

..There have been no reports on the HB-EGF, BTC and EPR expression in mesenchymal malignancies of fibrohistiocytic origin including malignant fibrous histiocytoma (MFH)...

..0446). These findings strongly indicate that the HGF/c-Met signaling system plays an important role in promoting cell proliferation of human MFHs via an autocrine loop...

..Surgical excision of the bursa was curative. To our knowledge, multiplanar reconstruction CT and arthroscopic features of the isolated suprapatellar bursitis have not been illustrated previously...

..Little information is available regarding the expression of platelet-derived growth factor (PDGF) isoforms and their receptors in soft tissue malignant fibrous histiocytoma (MFH)...

..Bone defects after excision of malignant bone and soft tissue tumors are usually reconstructed by autogenous bone grafting or allografting...

..The association between the tumor and Sprengel's deformity has never been reported previously. Antecedent surgical trauma might play a role in the development of this tumor...

..The inhibitory effect of ST1571 on cell proliferation in these three cell lines might be due to decreased tyrosine kinase activity. STI571 might be a potent chemotherapeutic agent for human MFHs...

..The coexistence of pregnancy and liposarcoma is rare. Only 12 cases of pregnancy-associated liposarcoma have previously been reported in the English-language literature...

..The diagnostic role of fine-needle aspiration biopsy (FNAB) of bone lesions is not yet fully understood. The aim of this study was to examine the diagnostic accuracy and reliability of FNAB of bone lesions...

..There was no evidence of pre-existing lesions. Total excision of the tumor was curative...

..Total excision of the tumor was curative. This is the second reported case of intracortical lipoma...

..In the present case, because MR imaging demonstrated extensive signal abnormalities involving the apophysis, periosteum, and intramedullary portion of bone, a neoplasm could not be excluded, and a biopsy was undertaken...

..Plain computed tomographic (CT) scans showed a lesion with isodensity to muscle. The lesion showed no enhancement on postcontrast CT scans...

..Specific FNAB diagnoses were correct in 151 of 279 cases (54%) in combination with clinical and radiologic findings. FNAB is a valuable technique for the primary diagnosis of soft-tissue lesions...

..This prospective study analyzed preoperative and postoperative dynamic changes of the spinal cord in patients with cervical spondylotic myelopathy...

..The expression of c-kit and/or its ligand, stem cell factor (SCF), has been related to tumor proliferation, in several tumor systems...

..TNAB revealed noncaseating epithelioid cell granulomas in association with multinucleated giant cells. Combined with the radiologic findings, TNAB is considered a useful modality for the diagnosis of nodular muscular sarcoidosis...

..The postoperative course was uneventful, and he remains well 3 years after his operation without persistent infection or allograft rejection...

..A biologic reconstruction with a precise anatomic fit is possible, and long-term endoprosthetic problems and maintenance of bone-banking facilities for allografts are avoided...

..Exogenous application of TGF-beta1 was confirmed to increase collagen synthesis of the LFCs. This data indicated that mechanical stretching force can promote TGF-beta1 production by LFCs, resulting in hypertrophy of the ligament...

..CONCLUSIONS: Spinous process-splitting laminoplasty increases the degree of freedom of the spinal cord...
