The typical lesion may be identical to a squamous papilloma, but it tends to have pointed or verruciform surface projections, to have a very narrow stalk, to be white from considerable surface keratin, and to present as multiple or clustered individual lesions (Figure 4).
Koilocytes (HPV-altered epithelial cells with perinuclear clear spaces and nuclear pyknosis) may or may not be found in the superficial layers of the epithelium (Figure 7) and occasional lesions have focal areas covered by mixed bacterial colonies, perhaps with mild, irregular destruction of the otherwise smooth surface of the keratin beneath the colonies.
The condyloma, moreover, is seldom pedunculated with a stalk, as is typical of the papilloma.
