Fig. 8From: Intraosseous intraneural perineurioma derived from the inferior alveolar nerve with an abnormality of chromosome 22 and expression of the BCR-ABL fusion gene: report of a case and review of recent literatureFISH (fluorescent in situ hybridization) method. a The BCR-ABL fusion gene shows a yellow signal. A yellow signal was observed, and expression of BCR-ABL fusion gene was confirmed (white arrow). b An orange signal indicates ABL gene and a green signal indicates BCR gene. Cells with one green signal of BCR gene were observed, and lack of BCR region was confirmed (white arrow)Back to article page
