Fig. 4From: Extraskeletal myxoid chondrosarcoma of the gingival: a rare case report and review of the literatureFISH images of the tumor. Orange (R) signal marks the 3 'end of NR4A3 gene, green (G) signal marks the 5 'end of NR4A3 gene. The normal signal mode is 2F (F is the yellow signal of red-green fusion), and the typical positive signal mode is 1F1R1G. FISH analysis on the histological section evidenced rearrangement of NR4A3 gene(arrow)Back to article page
