Aspiration biopsy cytology of metastatic extraskeletal myxoid chondrosarcoma and its cytologic differential diagnosis.
Transabdominal fine needle aspiration biopsy of a metastatic myxoid chondrosarcoma in retroperitoneal spaces revealed amorphous mucoid material containing clusters of chondroblasts with round hyperchromatic nuclei and scanty cytoplasm, pleomorphic mesenchymal cells with round nuclei and vacuolated cytoplasm and groups of immature cartilaginous cells with single or double nuclei and fibrillar or filmy cytoplasm. The cytologic differential diagnosis between myxoid chondrosarcoma and other myxomatous tumors of bone and soft tissue is discussed.
