title: Mastication of verruca vulgaris associated with esophageal papilloma: HPV-45 sequences detected in oral and cutaneous tissues.
abstract: Human papillomaviruses (HPVs) are double-stranded, circular, epitheliotropic DNA viruses of which nearly 70 types have been identified. Specific HPV types exhibit a predilection to infect certain sites; however, occurrence is not unique or restricted to these sites. HPV typing may also be helpful in determining the oncogenic potential of HPV lesions. The most common HPV types, 6 and 11, are associated with benign mucosal lesions, whereas types 18, 16, 31, and 33 are thought to confer a high rate of malignant transformation. We describe a patient with both palmar verrucae and esophageal papillomatosis that proved to be HPV type 45 by polymerase chain reaction. HPV 45 has a high homology to HPV 18 and is a member of the relatively new "high-risk" mucosal HPV family in terms of cervical oncogenic potential. To our knowledge, HPV 45 has never been reported in cutaneous warts or esophageal lesions.
