title: DNA from human polyomaviruses, TSPyV, MWPyV, HPyV6, 7 and 9 was not detected in primary mucosal melanomas.
abstract: OBJECTIVE
  Mucosal melanomas arise in non UV-light exposed areas and causative factors are yet unknown. Human polyomaviruses (HPyVs) are rapidly increasing in numbers and are potentially oncogenic, as has been established for MCPyV in Merkel cell carcinoma, an unusual skin cancer type. The aim of the present study was to investigate the association between TSPyV, MWPyV, HPyV6, 7 and 9 and mucosal melanoma.
  
  
  METHODS
  Fifty-five mucosal melanomas, were analyzed by a Luminex assay, for the presence of 10 HPyVs (BKPyV, JCPyV, KIPyV, WUPyV, TSPyV, MWPyV, HPyV6, 7 and 9) and two primate viruses (SV40 and LPyV).
  
  
  RESULTS
  In 37 samples the DNA quality was satisfactory for analysis. However, none of the samples analyzed were positive for any of the examined viruses.
  
  
  CONCLUSIONS
  None of the above-analyzed HPyVs were detected in mucosal melanoma samples, and they are for this reason unlikely to play a major role in the development of this tumor type.
