    Abstract:
    The extent to which the clinical diagnosis of male condylomata acuminata (CA) will be improved by histopathologic examination, immunohistochemical demonstration of papillomavirus common antigen (BPV), or demonstration of human papillomavirus (HPV)-specific DNA was studied. The relation of nuclear atypia to local cytodestructive therapy and specific HPV types was also analyzed. Altogether, the diagnosis could be histologically verified in 116 of 133 (87%) patients with clinically suspected penile CA. Of these, 69 (59%) had a positive result in in situ DNA hybridization for one or more of HPV types 6/11, 16/18, 31/33/35, or 31/35/51. Atypical cells were observed in 53 CA biopsies (46%), and there was a statistically significant correlation between this finding and the high risk HPV types 16/18, 31/33/35, and 31/35/51. Seventeen patients had neither histologic signs of condyloma acuminatum, nor detectable BPV antigen, and in situ hybridization showed HPV type 31/33/35 DNA in one biopsy, and HPV type 6/11 DNA in another. No correlation between the atypical changes and the type of previous therapy for the warts was found. Our results indicate that histopathologic examination supplemented with new HPV-specific methods is an important tool in diagnosing HPV infections.
