ABSTRACT
Verrucous carcinoma as a well differentiated squamous cell carcinoma appeared in skin and mucosa, so called Ackerman's tumor, is a slow-growing tumor with local infiltration rather than the tendency of metastasis. Though this tumor has been reported by many authors since named by Ackerman, despite the relatively small number of skin cancers, the difficulty in diagnosis due to benignity and pathologic finding and the high recurrence rate has aroused the interest in the disease. In addition, the premalignant region or pathogenesis has not been discovered clearly yet, besides the assosiation with chewing tabacco, but such as the correlation with hereditary carcinogenic factor(gene) in etiology with recent molecular biological approach has been clarified steadly. In the 51-year-old male patient with 1.5 x 1.5cm verrucous carcinoma originating from lower lip, it was possible to achieve a good result in terms of both aethetics and function with the use of surgical excision. Since 1980 when one case originating from postauricular area was reported in 1980, there has been no reports on the case from oral cavity in Korea. Therefore, we report one case of verrucous carcinoma from lower lip, experienced for the first time, on this literature.
