Epidermodysplasia verruciformis is a rare, heritable disease characterized by an unusual susceptibility to infection with specific types of human papillomavirus and a propensity for developing malignant skin tumours. Partial defects in cell-mediated immunity have been demonstrated in this disease. In the present report, a young patient with epidermodysplasia verruciformis who was treated succes...

Epidermodysplasia verruciformis is an inherited disorder, characterized by multiple plane warts, pityriasis versicolor-like lesions, defects of cell-mediated immunity, and tendency to develop skin malignancies, primarily on sun-exposed areas. In this article, we present a case of epidermodysplasia verruciformis with multiple plane warts, pityriasis versicolor-like lesions, and squamous cell car...

An epidermodysplasia verruciformis patient suffering from generalized warts and a carcinoma at the forehead was found to be infected by at least six types and subtypes of human papillomaviruses. The central part of the carcinoma, however, harbored only human papillomavirus 5 DNA. The DNA persisted extrachromosomally in high genome copy number. In contrast to wart DNA preparations, a significant...

Background: Epidermodysplasia verruciformis (EV) is a skin disease associated with numerous early onset viral warts on the sun exposed parts of the body that usually progress into different skin malignancies. Kidney transplant patients are also commonly associated with viral warts that might change into skin cancers. Objective: To re-evaluate all features of the acquired epidermodysplasia verru...

β-Human papillomaviruses (HPVs) cause near ubiquitous latent skin infection within long-lived hair follicle (HF) keratinocyte stem cells. In patients with epidermodysplasia verruciformis, β-HPV viral replication is associated with skin keratosis and cutaneous squamous cell carcinoma. To determine the role of HF keratinocyte stem cells in β-HPV-induced skin carcinogenesis, we utilized a transgen...

The involvement of human papillomavirus (HPV) in skin carcinogenesis in a patient with epidermodysplasia verruciformis was studied. This patient had disseminated pityriasis versicolor-like lesions, flat warts, and a malignant skin carcinoma. HPV types 3, 17, 20 (HPV-20), and 38 were isolated and molecularly cloned from the benign skin lesions of this patient. Of these HPVs, only HPV-20 was dete...

carcinoma. Lesions from a case in which papovavirus was evident were transmitted to a healthy person, the virus being found in cell nuclei in the wart lesions and also in lesions with some signs of atypia. This fulfilled the condition for recognition of the virus, demonstrated by electron microscopy, as being causatively involved in the verrucous lesions in epidermodysplasia verruciformis and a...
