Abstract
- Verrucous cyst is a rare form of epidermal cyst showing verrucous changes of their stratified squamous epithelial lining, characterized by papillomatosis, acanthosis, and hypergranulosis with large, irregular keratohyaline granules. In addition, vacuolated keratinocytes, parakeratosis, and squamous eddies are often present. Herein, we describe a 45-year-old woman with a verrucous cyst, which occurred on left axilla three months ago, showing the above-mentioned characteristic histologic features. Both the immunohistochemical stain and polymerase chain reaction for the common antigen for human papillomavirus and DNA chip study for the human papillomavirus were negative.
