[Male genital lesions caused by papillomaviruses. Importance of colposcopy].

Ten years after the description of cervical flat condyloma, it is now admitted that Human Papillomaviruses (HPVs) type 6 and 11 are responsible for condylomata acuminata and typical flat condyloma of the uterine cervix. HPV DNA type 16 and, less frequently, 18, 33 and other as yet uncharacterized HPV types (G. Orth, personal communication), are found in the majority of Cervical Intraepithelial Neoplasia (CIN), Vulvar Intraepithelial Neoplasia (VIN) and cervical and vulvar invasive cancers. Since HPVs are sexually transmissible, recent interest has focused on the "male factor". Clinically detectable lesions of male genitalia are condylomata acuminata, bowenoid papulosis and flat condyloma-like papules. The aim of our study was the colposcopical screening, recently suggested, of different groups of male patients in order to detect HPV-related lesions and the description of the colposcopical features of subclinical HPV-related lesions, since most of them have never been reported, to our knowledge, in the literature. A total of 114 men were examined. Among them, 18 presented clinically detected recalcitrant condylomata acuminata, 28 had been treated for the same pathology 1 to 5 days earlier and were clinically free of lesions, 46 were sexual partners of women with cervical atypia (flat condyloma and/or CIN) and 22 had a clinical diagnosis of genital infection without HPV-related lesions. A careful examination of external genitalia was performed. Then all patients underwent penile colposcopy before and after application of 5 p. 100 acetic acid. Selected biopsies were performed in all lesions which were clinically and colposcopically different from classic warts. Colpophotographs were taken in all cases.(ABSTRACT TRUNCATED AT 250 WORDS)
