چکیده
Tumors produced by 2-acetylaminofluorene occur with differing frequencies in various organs. The squamous-cell carcinomas of the auditory canal region, reported in the original experiment of Wilson, De Eds, and Cox (23), appear to be of particular interest. There has been considerable discussion in the literature as to their site of origin and mode of development. In our experiment this type of tumor was the most frequent one. This st imulated our interest in further investigation of the factors involved in their pathogenesis.
