title: Human papillomavirus and skin tags: is there any association?
abstract: BACKGROUND
  Low-risk human papillomavirus (HPV) infections are related to the genesis of various benign lesions. In an isolated report available, HPVs have been implicated in the causation of skin tags too.
  
  
  OBJECTIVE
  The present study was designed to detect the existence of low-risk HPV types 6 and 11 in cutaneous soft fibromas (skin tag) in north Indians.
  
  
  METHODS
  A total of 37 cases of skin tags from various sites were analyzed. Highly sensitive and comprehensive polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) assays were done for the detection of low-risk HPV types 6 and 11.
  
  
  RESULTS
  The results revealed the presence of HPV DNA 6/11 in 48.6% of the skin tags examined by PCR-RFLP.
  
  
  CONCLUSIONS
  This result corroborates the hypothesis that HPV plays a part in the etiology of benign lesions like cutaneous soft fibromas. The identification of HPV 6/11 in these lesions, which are benign proliferations of the skin, further expands the spectrum of HPV-linked lesions.
