Squamous odontogenic tumor (SOT) is a rare benign epithelial odontogenic neoplasm of the jaws. Both intraosseous and peripheral SOTs have been described in the English language literature. While most intraosseous SOTs occur as solitary lesions, a multicentric variant has also been previously described. Although the radiographic and microscopic features are identical for both solitary and multicentric clinical presentations, there are three significant differences between them. More specifically, multicentric SOT presents at an earlier age (third decade of life), has a slightly higher male to female ratio than the solitary type and has a marked predilection for African-Americans. Here we document the eighth reported case of multicentric SOT, which was diagnosed in a 43-year-old AfricanAmerican male. In addition, we feature focal sebaceous metaplasia, a heretofore unknown microscopic feature of SOT. Clinical, radiological, and histopathological findings are discussed. The differential diagnosis, biological behavior and management modalities for SOT are also addressed.

In the first study presented in this article, 852 adolescents rated their favorableness toward new technology. When there were significant differences, males, and older adolescents tended to be more favorable toward technological issues than females or younger adolescents. In the second study, 158 mothers of adolescents from the first study said whether they had made efforts to help their adolescents develop technical skills. Adolescents' attitudes toward technology were sensitive to mothers' education and whether or not mothers helped their adolescents to develop technological skills. Mothers helping made a difference in youths whose mothers had less education; those youths whose mothers helped showed a more favorable attitude than those whose mothers did not help. Adolescents whose mothers had a college education were favorable toward technology whether or not their mothers helped. Results support the emerging view that family factors are central to adolescents'career development.
