BACKGROUND: Malignant neoplasms with lesions of the chest are quite rare in sternum and range from 0.5 to 3.1% total number patients bone tumors all localizations. In this connection, there few publications describing tactics surgical treatment methods prosthetics formed defect. The present article describes a clinical case successful application an individual prosthesis manubrium G1 chondrosar...

Hedgehog (Hh) pathway inhibition in cancer has been evaluated in both the ligand-independent and ligand-dependent settings, where Hh signaling occurs either directly within the cancer cells or within the nonmalignant cells of the tumor microenvironment. Chondrosarcoma is a malignant tumor of cartilage in which there is ligand-dependent activation of Hh signaling. IPI-926 is a potent, orally del...

Extraskeletal myxoid chondrosarcoma (EMC) is an uncommon but distinct entity with clearly different clinicopathological, immunohistochemical, cytogenetical and histogenetical features from conventional skeletal chondrosarcoma. Because of its better prognosis in comparison to conventional skeletal chondrosarcoma, the right diagnosis is essential. A case of EMC occuring in the external auditory m...

BACKGROUND Chondrosarcomas are the second most frequent primary malignant type of bone tumor. No effective systemic treatment has been identified in advanced or adjuvant phases for chondrosarcoma. The aim of the present study was to determine the antitumor effects of doxorubicin and everolimus, an mTOR inhibitor on chondrosarcoma progression. METHODS AND FINDINGS Doxorubin and/or everolimus w...

Mammary sarcomas are uncommon tumors. Of these pure chondrosarcoma without any other area of epithelial or mesenchymal differentiation feature as even rarer. This excludes tumors like malignant cystosarcoma phyllodes and metaplastic carcinoma where malignant cartilaginous areas may be present. Further primary chondrosarcoma arises from breast stroma and not from underlying bone or cartilage. On...

Three cases of intracranial dural chondrosarcoma are reported. The radiologic appearance of this slow-growing, extraaxial malignant tumor is different from the more familiar skull-base chondrosarcoma and may mimic an atypical meningioma. Dural chondrosarcoma tends to be less calcified or even to lack matrix calcification; it is associated with bone erosion but not with bone destruction or hyper...

Chondrosarcoma is a rare entity of malignant tumor which arises from cartilaginous tissue, and the literatures on this disease are scarce. The first-line of treatment for cardiac chondrosarcoma is surgery. Due to early local recurrence and distant metastasis, the prognosis is poor even after complete surgical excision. We present a case of chondrosarcoma in the left atrium causing functional mi...

Chondrosarcoma is a malignant tumor originating in cartilaginous cells. And there are only few reports of the case of chondrosarcoma in temporomandibular joint. We discuss a case of chondrosarcoma in temporomandibular joint in a 28-year-old man. Tumor was in contact with the dura, but en bloc resection was performed. After surgical resection of the tumor, face defect was reconstructed by rectus...

Chondrosarcoma is a common malignant bone tumor, which accounts for 20% of all malignant bone tumors. It often occurs in the long bones, but the incidence of scapular chondrosarcoma is rare. Here, we describe a case of a large chondrosarcoma occurring in the scapula which was treated with Malawer limb salvage surgery. The patient retained considerable limb function after complete removal of the...

Extraskeletal chondrosarcoma in anterior mediastinum is very rare. A 45-year-old male patient was admitted to the hospital with precordial chest pain. A large and well-shaped mass in the anterior mediastinum was seen radiologically, and there was a clearly compression of the heart by the mass. The lesion was totally resected, and extraskeletal mediastinal chondrosarcoma was histopathologically ...
