Dozens of lawyers who have filed lawsuits on behalf of more than 200 women alleging that a former campus gynecologist at the University of Southern California sexually abused them are pursuing cases on separate tracks, with the first court hearings set for next month.

So far, nearly 50 lawsuits have been filed against USC and Dr. George Tyndall, the campus gynecologist for more than two decades. The plaintiffs, most of whom sued anonymously, claim Tyndall made inappropriate remarks and performed unnecessary procedures on female students.
