We describe a 28-year-old woman with characteristic clinical signs of Comèl–Netherton syndrome (CNS) who showed numerous plane warts on her face and forearms and papillomatous skin tumours affecting her groins and genitoanal skin. Using human papillomavirus (HPV) type-specific primers for cutaneous and mucosal HPV types we identified HPV 16-specific sequences in plane warts and HPV 51- and HPV 52-specific DNA in papillomatous skin from the patient's groins, suggesting a pathogenetic role (cofactor) for HPV in the development of verrucous skin lesions in patients with CNS. Whether the susceptibility to HPV infections is due to decreased cellular immunity or epidermal defence mechanisms remains to be seen.
