Is the brown on the fruit itself, or on the leaves.
If you could include a picture that would be helpful.

Apparently it's quite common with this type of Tom.

Not sure really what the brown marks are, other than something rubbing against the fruit.

They look more like plum tomatoes than beefsteak ones.

I have something similar on a few of my toms, not all. I think it's caused by damage to the skin, in my case hail while the toms were still very small. It certainly doesn't seem to be spreading.
 
Mind you, I'm only surmising so maybe someone with greater expertise will be able to tell us otherwise.
