[Verrucous carcinoma and Buschke-Lowenstein tumors: apropos of 2 cases].

The authors present two cases of verrucous carcinomas on Buschke-Lowenstein tumor. The Buschke-Lowenstein tumor is an epithelial sexually transmissible benign tumor of viral origin. Under the influence of oncogenic papillomavirus types 16 and 18 it can become malignant tumor which relations with the verrucous carcinoma, tumor with low grade and essentially local malignancy are still discussed. This evolution follows the alteration by a viral protein of the functions of the tumor suppressor protein P 53. The surgery remains the reference treatment although there is a possibility of frequent recurrences. Radiation therapy and chemotherapy were suggested as adjuvant treatments for the complicated sorts.
