Big Tom Callahan (Brian Dennehy) is the street-smart owner of a company that makes auto parts, and one day he'd like his son Tommy Callahan III (Chris Farley) to take over the business. Trouble is, Tommy Boy is a fat, dim-witted slob who took seven years to get a business degree and has no idea how to run a business. His father's sudden death unexpectedly puts Tommy Boy in charge, with his dad's weasely assistant Richard (David Spade) trying to guide him.
Odontogenic tumors are any kind of abnormal growth in and around the jaw and teeth. 1  Many of these tumors are considered to be benign.  In unusual cases, odontogenic tumors are malignant, meaning they are likely to spread.
The most common tumor of the mandible and maxilla is squamous cell carcinoma invading the bone through dental sockets. These can involve any portion of the intraoral mandible or maxilla. Ameloblastoma, the most common epithelial odontogenic tumor, usually arises in the posterior mandible.
