As there are no evidence-based recommendations for margin control in head and neck
chondrosarcomas, broadening our discussion to include the optimal treatment for whole body
chondrosarcomas warrants consideration.
One of the main concerns of patients with Maffucci syndrome is the malignant transformation of the enchondromas into
chondrosarcomas and the hemangiomas into vascular malignancies.
[sup][4],[5],[6],[7],[8],[9] Low PDCD5 expression correlates highly with poor prognosis for gastric cancer, clear cell kidney cancer, and
chondrosarcoma. [sup][4] These studies indicate that PDCD5 protects against tumorigenesis and tumor progression.
The pathological findings observed in the present case are similar to those described for
chondrosarcomas of other affected domestic animals (DITTMER et al., 2012; THOMPSON & POOL, 2002).
Temporal bone
chondrosarcomas have been mistaken for multiple sclerosis, glomus jugulare tumors, meningiomas, and chordomas.
Although
chondrosarcomas are considered the most common primary malignancy of the chest wall and sternum, it is nevertheless a rare lesion as reported in the literature.
Canine sinonasal skeletal neoplasms:
chondrosarcomas and osteosarcomas.
Extraskeletal myxoid
chondrosarcoma (EMC) is an uncommon low-grade sarcoma of the soft tissue, usually presenting as a slow-growing mass in men in their fifth to sixth decades.[sup.1] It is characterized by a multinodular growth of primitive chondroblast-like cells in an abundant myxoid matrix.
Assessment of Proliferative Potentials of Canine Osteosarcomas and
Chondrosarcomas by MIB-1 Immunohistochemistry and Bromodeoxyuridine Incorporation.
There is often a periosteal reaction, and osteosarcomas and
chondrosarcomas typically show areas of ossification.
It should be noted that approximately 3% of bone tumours occur in the foot or ankle.2,3
Chondrosarcomas (CHS) are tumours that develop during adulthood and old age, with maximum number of incidences between the fourth and sixth decades of life.
Similar to other
chondrosarcomas, the cartilaginous component is strongly positive for S100 protein.
Effectiveness and safety of spot scanning proton radiation therapy for chordomas and
chondrosarcomas of the skull base: first long-term report.
(1) Primary nasopharyngeal ESMC can often be misdiagnosed with squamous cell carcinoma nasopharynx, melanomas, lymphomas, soft tissue sarcomas, Ewing sarcoma, skeletal
chondrosarcomas, chordomas, parachordomas, myoepithelial carcinoma, myxopapillary ependymomas, chordoid meningiomas, and myxoid liposarcoma.
