title: A case of a human-papillomavirus-60-induced wart with clinical appearance of both pigmented and ridged warts.
abstract: Human papillomavirus (HPV) type 60 infection is histologically associated with characteristic homogeneous intracytoplasmic inclusion bodies. However, it remains unclear whether the virus is associated with cystic, pigmented or ridged plantar warts. We report a 51-year-old Japanese female with a HPV-60-induced plantar wart which showed the clinical appearance of both pigmented and ridged warts. Masson-Fontana staining revealed increased melanin granules in the epidermis of the wart. This observation suggests that HPV-60 may be associated not only with cystic warts but also with the specific morphology of ridged warts, and the biological disorder of hyperpigmentation may be controlled by additional unknown factors which differ from case to case.
