[Verrucous Carcinoma (L. V. Ackerman)].

Characteristics of the Verrucous Carcinoma as described by L. V. Ackerman in 1947: strictly lokalized tumor, no metastatic spread, yet strong tendency to recidivity. Note: 1. In the case of inadequate excision a too optimistic evaluation by the pathologist frequently occurs. 2. In the case of lesions of the oral mucosa as a consequence of irradiation a dramatic increase in malignancy has been observed. 3. Therapy of choice: radical excision.
