Intracranial mesenchymal chondrosarcoma is one of the rare tumors of the central nervous system, which often presents as an aggressive-appearing extra-axial hypervascular tumor at the falx cerebri. The tumor presents mostly in young adults, while meningioma or metastatic intracranial tumor most commonly in aged people. However, its imaging findings are non-specific. In this article, we present ...
Mesenchymal chondrosarcoma (MC) is a rare variety of chondrosarcoma (CS), which is both clinically unique and histologically distinct compared with conventional CS. Maxillofacial MCs are aggressive, have a tendency for recurrence and significant distant metastasis to lung and bone, and are associated with overall poor prognosis. Histopathologically, it is a biphasic tumor comprising of islands ...
Cytokines produced in the tumour microenvironment exert an important role in cancer pathogenesis and in the inhibition of disease progression. Cancer of the cartilage is termed metastatic chondrosarcoma; however, the signaling events resulting in mesenchymal cell transformation to sarcoma have yet to be fully elucidated. The present study aimed to characterize the cytokine expression profile in...
BACKGROUND Chondrosarcoma of the bladder is an extremely rare disease. Only five previously described cases are known in the medical literature. PATIENTS AND METHODS We present a chondrosarcoma developed 19 years after radiation treatment in a 73-year-old patient. A literature search of articles published from 1984 to 2014 was performed. RESULTS This is the first reported case of post-radia...
Mesenchymal chondrosarcomas are a rare variant of primary chondrosarcomas and can pose a diagnostic dilemma, especially when the features on conventional imaging are equivocal for an aggressive lesion. There is very little PET-CT experience in mesenchymal chondrosarcomas as per the literature and to the best of our knowledge, we are the first to describe a maxillary mesenchymal chondrosarcoma o...
Carcinosarcoma is a rare tumor composed of variable proportions of carcinomatous and sarcomatous elements and comprises less than one percent of all gallbladder malignancies. In most reported cases of carcinosarcoma of gallbladder, the epithelial component is adenocarcinoma. The mesenchymal component varies from homogenous sarcoma to more heterotopic elements like malignant bone, cartilage, and...
A 13-year-old castrated male Maltese dog was presented to a local animal hospital with an oral hemorrhage. An intraoral examination revealed irregular proliferated lobular mass at the right side of maxillary gingiva and hard palate. surgically excised requested for histopathology examination. Histopathologically, neoplastic foci were composed biphasic morphologic patterns, such as primitive mes...
BACKGROUND Primary mesenchymal chondrosarcoma of the kidney is an extremely rare malignant tumor. To our best knowledge, only 9 such cases have been reported so far. CASE PRESENTATION In the current paper, we present the case of a 67 year-old patient with recurrent left lumbar pain, increased fatigability and intermittent macroscopic hematuria. He underwent a surgical resection of the left ki...
Chondrosarcoma is a malignant mesenchymal tumour of cartilaginous origin. It represents 11% of all malignant primary bone tumours, and the pelvis, ribs, femur and humerus are most frequently involved. Chondrosarcoma of the head and neck region is a rare disease, and represents approximately 0.1% of all head and neck neoplasms. This report describes a rare localisation of chondrosarcoma in a 56-...
