title: Pyogenic granuloma following treatment of verruca vulgaris with cryotherapy and Duoplant.
abstract: We report an unusual case of pyogenic granuloma that appeared after the application of liquid nitrogen and 27 percent salicylic acid (Duoplant, Stiefel Inc.) to a verruca vulgaris. Only two cases of pyogenic granuloma following cryotherapy appear in the literature and pyogenic granuloma as a complication of salicylic acid application has not been documented.
