A series of extraskeletal myxoid chondrosarcomas with rare morphological and molecular variations.

Key Points

• The study aims to explore the morphological and molecular variations in extraskeletal myxoid chondrosarcomas (EMC).
• Case series involving five patients with EMC
• Analysis of histological features
• Investigation of genetic alterations and fusion partners
• Significantly greater histological diversity observed than previously documented
• Identification of novel fusion partners expanding the genetic understanding of EMC
