Comments

A 60-year-old man presented with a 2 year history of extensive periungueal redness and scaling of the right index finger. A biopsy showed Bowen disease of the nail bed, a distinctive variant of squamous cell carcinoma that can spread to other nails over months to years. Periungual Bowen disease can be distinguished from common warts by the presence of scaling and onycholysis that is out of proportion to the extent of verrucous changes. In this case, the redness is most prominent in the skin overlying the matrix. Human papillomavirus type 16 has been reported in association with Bowen disease of the nail bed and periungual skin.

Description
