Abstract
|
|
|
Chondrosarcoma is a commonly encountered malignant cartilaginous tumor. However, only 1% of chondrosarcomas arise in the extraskeletal region. The pathologic types of this tumor include mesenchymal, myxoid, and low grade. A mesenchymal chondrosarcoma is a rare, highly malignant cartilaginous tumor that is rarely encountered, and it shows similar imaging features to other malignant soft-tissue tumors. Here, we report a mesenchymal chondrosarcoma presenting as a palpable mass in the neck, arising in the carotid space, which is also known as the retrostyloid parapharyngeal space.
