Myxoid chondrosarcoma : cytology FNA
The rare high-grade variant of extraskeletal myxoid chondrosarcoma is characterized by cords of large epithelioid cells in a myxoid matrix. Like conventional extraskeletal myxoid chondrosarcoma, the high grade form may show rhabdoid cytomorphology, mimicking the plasmacytoid cells with nuclear atypia seen in some myoepithelial carcinomas.
Extraskeletal myxoid chondrosarcomas (EMCs) are characterized by recurrent chromosome translocations resulting in fusions of the nuclear receptor TEC to various NH(2)-terminal partners.
