BACKGROUND Chondrosarcoma is a malignant tumor of chondrogenic origin and the mesenchymal type is a very rare finding. Mesenchymal chondrosarcoma tends to develop mostly in the skeleton but may also occur as a primary tumor in periosteal nervous and muscular tissues, the anterior cerebral falx, meninges, brain, maxillary sinus, eyelid, thyroid, pleura and mediastinum, while in the abdomen the m...

Chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. It is more common in older age and often affects the axial skeleton. We report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. A 40 yr woman presented with decreasing visual acuity and headache. Magnetic resonance (MR) image revealed a cystic sellar and suprasellar...

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...

Primary chondrosarcoma is a rare malignant tumor. The five types of chondrosarcomas are: central, peripheral, mesenchymal, differentiated and clear cell. The classic chondrosarcomas are central (arising within a bone) or peripheral (arising from the surface of a bone). We describe a patient with central chondrosarcoma of the humerus who underwent surgery and only two weeks later presented with ...

Introduction: Mesenchymal chondrosarcoma is a malignant tumor which originates from chondrogenic tissue. Agressive surgery is considered the major treatment method for the primary disease but there may be unsatisfactory results of surgery depending on location or extension to unresectable sites of majority of mesenchymal chondrosarcomas. Hemihyperplasia, formerly called hemihypertrophy, is a ra...

Chondrosarcoma is a malignant tumor of mesenchymal origin predominantly composed of cartilage-producing cells. This type of bone cancer is extremely resistant to radiotherapy and chemotherapy. Surgical resection is the primary treatment, but is often difficult and not always practical for metastatic disease, so more effective treatments are needed. In particular, it would be helpful to identify...

UNLABELLED Histological diagnosis and grading of cartilaginous tumors are closely correlated with patient prognosis; consequently, they are essential elements. We attempted to clarify the characteristics of 201Tl uptake in various histological types of cartilaginous tumors and to assess its clinical value. METHODS Twenty-two cases with histologically proven cartilaginous tumors (3 enchondroma...
