Cytologically malignant squamous-cell carcinoma arising in a verrucous carcinoma of the penis.
A case of verrucous carcinoma with a focus of cytologically malignant squamous-cell carcinoma is presented. This usually occurs following radiation therapy of the verrucous carcinoma, but may rarely occur de novo, as in this case. The potential usefulness of fine-needle aspiration in detecting focal anaplasia in verrucous carcinoma is discussed. This technique may be especially useful if the lesion is to be destroyed cryosurgically.
