There are few data available on the status of beta-catenin in rhabdomyosarcoma (RMS), another pediatric embryonal tumor. The aims of this study were 1st to verify the status of the exon 3 of CTNNB1 and 2nd to assess the usefulness of beta-catenin immunostaining in a small series of 8 embryonal RMS, 3 alveolar RMS, and 1 sclerosing RMS (SRMS). Sequence analysis revealed no mutations in the exon 3 of CTNNB1 in all the tumors studied. All RMS showed a cytoplasmic beta-catenin staining with cytoplasmic membrane reinforcement and no nuclear delocalization. We conclude that there is no evidence of beta-catenin mutation in the genesis of rhabdomyosarcoma and that beta-catenin does not represent a useful immunomarker to help distinguish between embryonal RMS and alveolar RMS.<\/jats:p>","DOI":"10.2350\/08-11-0553.1","type":"journal-article","created":{"date-parts":[[2009,2,17]],"date-time":"2009-02-17T10:36:14Z","timestamp":1234866974000},"page":"371-373","source":"Crossref","is-referenced-by-count":18,"title":["Beta-Catenin
