    Abstract:
    BACKGROUND: Evidence of vulvar human papillomavirus infection varies and the frequency of the different genotypes has not been adequately assessed. METHODS: Fifty consecutive sexually active healthy patients with vulvodynia and suspected of human papillomavirus infection underwent a vulvoscopy and biopsy. Ten normal vulvar samples were also enrolled as control. Histological and vulvoscopic findings were compared in relation to human papillomavirus-DNA presence and genotyping by a broad-spectrum polymerase chain reaction and reverse hybridization line probe assay. RESULTS: Although the clinical and histological diagnoses did not always coincide, a good association was found (p<0.0001). Human papillomavirus-DNA was detected in 42% of all biopsies and in none of the controls, and less frequently in acetowhite-positive patients (33.3%, p<0.03). Squamous papillomatosis (74%) was the most frequent histological diagnosis, followed by condyloma (20%). Condyloma (90%) but not squamous papillomatosis (29.7%) was significantly associated with human papillomavirus-DNA presence. Out of the vulvoscopically normal patients, one (33%) was human papillomavirus-DNA positive. Out of the recorded microscopic features, only koilocytosis was associated with human papillomavirus-DNA presence. Eight different human papillomavirus genotypes were detected: high-risk 16 (43%), 31 (19%), 52 (14.3%), 68, and 59 (4.8% each), and low-risk types 6 (71.4%), 11, and 40 (4.8% each); 33.3% of infections were multiple, ranging from 2 to 4 genotypes. Out of the human papillomavirus-DNA positive squamous papillomatosis, 72.7% showed a high-risk type but the infection remained episomal. CONCLUSIONS: Our data confirm human papillomavirus as a frequent cause of vulvodynia and its frequent association with squamous papillomatosis or condyloma. The high-risk human papillomavirus in squamous papillomatosis suggests screening for possible undiagnosed cervical infection.
