(Reuters Health) – Nearly three-quarters of U.S. dermatologists received payments worth a collective $34 million from drug companies in 2014, according to a new analysis of a public database.

In most cases, the payments were worth less than $50, researchers found. But a few doctors were taking industry payments worth at least $93,622.

“Most dermatologist in the U.S. – about 73 percent according to this database – received some form of payment from industry,” said lead author Dr. Marie Leger, a dermatologist at Weill Cornell Medicine and NewYork-Presbyterian in New York City. “That being said, most dermatologists get a modest amount from industry.”
