Cervical condyloma planum.

Condylomata were defined and described as wart-like lesions with papillary projections often observed on the skin and mucosa of the anogenital area. Cytologic, histologic, and colposcopic studies have demonstrated that the condylomatous lesion on the cervix presents itself more frequently as a flat lesion than a classical exophytic papillary one. Condyloma planum represents a new lesion on the human cervix, not described until 1977. 1,2 The viral etiology of this new type of condyloma has been confirmed in three ways: by the electron microscopic observation of human papillomavirus (HPV) particles, 1,3–8 by the identification of viral antigen using the peroxidaseantiperoxidase technique, 9–13 and by demonstrating the presence of the HPV DNA sequences using molecular cloning and hybridization techniques. 5,14
