Histopathologic changes in condylomata acuminata after application of podophyllum.

The histologic changes of podophyllin-treated condylomata acuminata were studied at 24-hour, 48-hour, and 7-day intervals. The 24-hour specimens had scattered individual atypical cells, whereas 48-hour specimens demonstrated small focal areas of atypia. Seven-day specimens exhibited very mild atypia of cells. All treated specimens had inflammation-necrosis ranging from scattered inflammatory cells to degeneration of the squamous epithelium.
