Does it look like the ones in this recent thread?
If so and the 'bruises' are only on the upper parts, one possibility for both threads is that hail (been a lot of it about this year) bruised the young fruit and let in brown rot spores. It could be scab as Dave said though. A photo might help to identify but always difficult with this type of problem.
