title: Pyoderma Vegetans Misdiagnosed as Verrucous Carcinoma.
abstract: Pyoderma vegetans, a rare disorder of the skin, is considered a highly specific marker for inflammatory bowel disease, especially ulcerative colitis. It is clinically characterized by large verrucous plaques with elevated borders and multiple pustules. Here, the authors report the case of a 33-year-old man who was misdiagnosed as having verrucous carcinoma for 4 years.
