The reason you seem to be receiving conflicting info, is because you are talking about two seperate things...contract obligations vs match obligations. If you match to a DO program, but decide not to honor your contract, you are free to walk away. However, that has nothing to do with your match obligations. If you match to a DO program (whether you sign your contract or not), you are automatically withdrawn from the MD match and will probably have to sit out a year. You MIGHT be allowed to scramble but your chances of scoring an allo derm spot would be impossibly low...to say the least. Also, when talking to other programs, you will be forced to explain why you wouldn't honor your contract. Bottom line, don't enter the DO match unless you are willing to live with the consequences.
