摘要: This study reports a case of papillary carcinoma with vesicular components showing multiclonal aberrations chromosome 22 as revealed by RHG-banding cytogenetics and fluorescence in situ hybridization (FISH; whole BCR-ABL-specific locus probes, multi-FISH). Four clones changes the sole abnormality were seen. The main abnormal clone lacked 22. A del(22)(q11) was observed second group cells. third had an idic(22). Finally, FISH fourth cell population der(17)t(?17;22). Some these alterations have been described other solid tumors such meningiomas neurinomas, suggesting common genetic pathway tumor progression occurring multistep process. Chromosome do not seem to be involved pure thyroid therefore could related maintenance follicular-type histological pattern.
