Extraskeletal myxoid chondrosarcoma (EMC) is a rare low-grade malignant mesenchymal neoplasm of the soft tissues, that differs from other sarcomas by unique histology and characteristic chromosomal translocation. There is an uncertain differentiation (there is no evidence yet showing that EMC exhibits the feature of cartilaginous differentiation) and neuroendocrine differentiation is even possible.
