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...

A case of primary chondrosarcoma of the testis is reported. A 40-year-old man presented a painless swelling of the right testis that he has been observing for 3 years. Gross examination of the resected specimen showed an encapsulated, gray to tan colored, roughly rounded tumor. Histologically, the tumor revealed a well-differentiated chondrosarcoma.

Periosteal chondrosarcomas, also known as juxtacortical are a rare subtype of chondrosarcoma. They usually present with pain and swelling over the affected site, most often arising in appendicular skeleton, metaphysis distal femur humerus common sites. In this poster we case report periosteal chondrosarcoma on internal surface right 8th rib, making an unusual site for such tumour. chondrosarcom...

Mesenchymal chondrosarcoma is rare in the extraskeletal system and is even more unusual in the orbit. There is little difficulty making a histologic diagnosis because it consists of islands of well-differentiated cartilage surrounded by undifferentiated mesenchymal cells arranged in a hemangiopericytoma-like pattern (1-5). We have seen two identical cases of orbital mesenchymal chondrosarcoma i...

BACKGROUND AND PURPOSE Chordoma and chondrosarcoma of the skull base are rare tumors with overlapping presentations and anatomic imaging features but different prognoses. We hypothesized that these tumors might be distinguished by using diffusion-weighted MR imaging. MATERIALS AND METHODS We retrospectively reviewed 19 patients with pathologically confirmed chordoma or chondrosarcoma who unde...

Chondrosarcoma is a type of highly malignant tumor with a potent capacity to invade locally and cause distant metastasis. Adiponectin is a protein hormone secreted predominantly by differentiated adipocytes. On the other hand, angiogenesis is a critical step in tumor growth and metastasis. However, the relationship of adiponectin with vascular endothelial growth factor-A (VEGF-A) expression and...

Chondrosarcoma of the larynx is a rare, low-grade malignancy in terms of histology and clinical behavior. We present an unusual case of laryngeal chondrosarcoma, which developed a large dedifferentiated component on recurrence after primary surgery. The diagnosis of dedifferentiation was suggested in view of the morphological and metabolic findings on hybrid positron-emission tomography/magneti...

UNLABELLED Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric imp...

DESCRIPTION A 45-year-old man was referred to our department for acute respiratory distress. Upon arrival, chest x-ray showed an acute pulmonary oedema (figure 1) with a pulmonary tumour. Transthoracic echocardiography revealed a mass obstructing the majority of the left atrium and protruding into the left ventricle (figure 1). Eighteen years ago, the patient had been diagnosed with a grade II ...
