Increased Prevalence of Human Papillomavirus in Hairs Plucked From Patients With Psoriasis Treated With Psoralen–UV-A

Abstract

The rate of HPV DNA positivity was significantly higher in groups A (73% [11/15]) and B (69% [24/35]) than in group C (36% [10/28]) (A + B vs C, P =.009; chi(2) test; age adjusted). Conclusion The prevalence of HPV in the skin (hair follicles) is increased in patients with psoriasis who have a history of PUVA exposure.
