The presence of human papillomavirus type 16 in squamous cell carcinoma of the proximal finger and reconstruction with a bilobed transposition flap.

In a 71 year old white female a clinically diagnosed keratoacanthoma on the dorsum of the right third finger was removed using Mohs micrographic surgery and histologically diagnosed as a squamous cell carcinoma. It was shown by dot blot hybridization to have HPV type 16 DNA in the tumor. The wound was reconstructed with a bilobed transposition flap.
