title: Association of human papillomavirus infection with palmoplantar epidermal cysts in Korean patients.
abstract: Human papillomavirus (HPV) infection can develop into many different kinds of diseases ranging from simple warts to carcinoma in situ. Some investigators have recently suggested that HPV infection could be closely related to palmoplantar epidermal cysts. The aim of this study was to determine the existence of HPV and its subtype in palmoplantar epidermal cysts of Korean patients. We investigated 13 cases of palmoplantar epidermal cysts by employing clinical, histopathological and immunohistochemical examinations. In addition, PCR was performed using HPV 57 and 60 type primers. Four of the 13 cases (30.8%) showed the distinct histopathological features of palmoplantar epidermal cysts such as parakeratosis, vacuolar structures and eosinophilic inclusion bodies and these 4 cases showed positive immunohistochemical staining reactions for HPV. PCR for HPV detected type 60-positive bands in 5 of the 13 cases (38.5%), which included the 4 cases that were positive for immunohistochemical staining. These results show that HPV is associated with some cases of palmoplantar epidermal cysts in Korean patients, suggesting that HPV may play a role in the pathogenesis of these cysts.
