Extensive thrombus formation in chondroblastic osteosarcoma
has been described in femoral veins with extension into the inferior vena cava, right atrium, and left pulmonary artery.
Molecular distinction of chondrosarcoma from chondroblastic osteosarcoma
through IDH1/2 mutations.
Although other studies have applied thresholds of 30% (17) to 50% (13) chondroid matrix for diagnosing chondroblastic osteosarcoma
, our choice of 5% appears to show prognostic significance by univariate analysis.
Abstract: We report a case of polyostotic chondroblastic osteosarcoma
in a kestrel (Falco tinnunculus) admitted to the Wildlife Rehabilitation and Rescue Center (Naples, Italy).
Based on histopathological findings, a diagnosis of chondroblastic osteosarcoma
While telangiectatic osteosarcoma was exclusively in the pediatric cohort, chondroblastic osteosarcoma
was relatively more abundant in the YA cohort.
One of the most common subtypes of gnathic osteosarcoma is chondroblastic osteosarcoma
, which is made up of malignant, osteoid-producing cells with admixed islands and lobules of malignant cartilaginous or chondrosarcomatous tissue (figure 2).
Intraoperative TEE for the management of pulmonary tumour embolism during chondroblastic osteosarcoma
may show stippled, punctate, or linear mineralization at radiography or CT, while fibroblastic osteosarcomas often present as a purely lytic, rather than sclerotic, lesion which must be differentiated from other lytic lesions such as malignant fibrous histiocytoma, fibrosarcoma, and giant cell tumor.
Histologically, periosteal osteosarcoma has the appearance of chondroblastic osteosarcoma
of intermediate grade.
Based on histologic examination (figure 2, B), the patient was diagnosed with a grade 3 chondroblastic osteosarcoma
. He was referred for chemotherapy and will be closely followed with serial MRIs.
