Fine needle aspiration cytology of primary extraskeletal myxoid chondrosarcoma. A case report.
BACKGROUND
Extraskeletal myxoid chondrosarcoma is a rare soft tissue tumor of the extremities. Since it usually lacks obvious chondroid differentiation on light microscopy, it needs to be distinguished from other myxoid soft tissue sarcomas.


METHODS
The diagnosis of extraskeletal myxoid chondrosarcoma was made on fine needle aspiration in a patient with a swelling in the right calf. Cellular myxoid fragments having round to oval cells with grooved nuclei arranged in a cordlike pattern suggested chondroid differentiation. The diagnosis was confirmed by histopathology.


CONCLUSIONS
Fine needle aspiration cytology can be diagnostic of extraskeletal myxoid chondrosarcoma even in the absence of obvious chondroid differentiation.
