Butcher's wart virus (HPV 7) infections in non-butchers

The analysis of a total of 654 benign and malignant lesions of the skin, genitalia, lungs and bronchi, intestine, kidneys, bladder, mammae, and of the head and neck region, resulted in the identification of human papilloma virus 7 (HPV 7) infections in 3 individuals. One of these was an ordinary "butcher's wart," whereas the other 2 patients have never been involved in meat-handling or farming. One of the latter revealed extensive verrucosis of hands, feet, axilla, neck, and face, persisting for about 27 years, with new lesions arising in the neck region. Particularly the new lesions showed filiform morphology. The second patient has, for a period of more than 2 years, been showing filiform papillomas in the face which recurred after surgical removal. These 2 patients appear to represent the first cases of HPV 7 infections in non-butchers or non-meathandlers.
