BACKGROUND notch receptors are critical determinants of cell fate in a variety of organisms. Notch signaling is involved in the chondrogenic specification of neural crest cells. Aberrant Notch activity has been implicated in numerous human diseases including cancers; however its role in chondrogenic tumors has not been clarified. METHOD tissue samples from a case of primary chondrosarcoma of ...
Chondrosarcoma is cartilage forming neoplasm which mostly occurs in pelvis, femur and humerous. rare the foot involvement of phalanges extremely rare. It a malignant mimics various epiphysial tumors clinically radiologically, so histopathology gold standard for confirming diagnosis. We report an unusual case Grade II 60 years old male, who complained swelling pain left great toe past two years,...
clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...
Synovial chondromatosis of the elbow is an uncommon condition. However, a chondrosarcoma arising from the former is remarkably rare. The authors report a case of an elbow chondrosarcoma secondary to synovial chondromatosis in a 38-year-old woman. Before the development of chondrosarcoma, the patient underwent 3 operations and 3 sessions of radiosynovectomy because of continuous recurrence of sy...
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...
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...
statement of problem: chondrosarcoma is a tumor which includes 10 percent of the bone primary tumors. its prevalence is half of the osteosarcoma and two times of ewing’s. the mean age of the patients ranges between 30-50 years of old. there is no significant sex or race predilection. the most common complaint is the presence of a painless and enlarging mass. its clinical course is described as ...
Chondrosarcomas are among the most malignant skeletal tumors. Dedifferentiated chondrosarcoma is a highly aggressive subtype of chondrosarcoma, with lung metastases developing within a few months of diagnosis in 90% of patients. In this paper we performed comparative analyses of the transcriptomes of five individual metastatic lung lesions that were surgically resected from a patient with dedif...
PURPOSE The prognostic factors of chondrosarcoma remain uncertain as only a few large studies with long-term follow-up have been reported. The aim of this study was to analyze oncological outcomes and prognostic factors. MATERIALS AND METHODS A retrospective review of oncological outcomes and prognostic factors was performed on 125 consecutive chondrosarcoma patients who underwent surgery at ...
Chondrosarcoma accounts for ~15% of all primary malignant bone tumors. Chondrosarcoma of the spine is rare, while intra-atrial tumor embolisms as a result of chondrosarcoma are extremely rare. In the present study, the case of a 70-year-old male with thoracic chondrosarcoma, who presented with a fever and exertional dyspnea, is reported. Following anti-infection treatment with cefoperazone sodi...
