title: Genital bowenoid papulosis--squamous cell carcinoma in situ.
abstract: The case of a patient with bowenoid papulosis of the penis is described. Although his lesions resembled those of condylomata acuminata, a biopsy showed squamous cell carcinoma in situ. This case and those described in previously published reports confirm that squamous cell carcinoma in situ may exist in a papillomatous form on the genitalia of young adults. Venereologists must be familiar with this entity and must not dismiss all verrucous and papillomatous genital growths as condylomata acuminata.
