From June 12, 2005: William Kapfer, an 88-year-old retiree, thought he was in good hands with Dr. Michael A. Rosin. A physician since 1978, Rosin was among the most respected dermatologists in Sarasota. And he was one of just two with intensive training in Mohs microscopic surgery, a state-of-the-art procedure effective in curing the most common types of skin cancer.

Over a span of four or five years, Kapfer often found himself in Rosin's office undergoing Mohs surgery. So often that he began to wonder if he really had as many skin cancers as the doctor diagnosed.

In April, Kapfer's doubts were confirmed: He was among dozens of elderly patients listed in a federal indictment that accuses Rosin of falsely diagnosing skin cancer and performing unnecessary.
