Unless they look really disfigured and the holes etc. look very deep and open (in which case disease/bugs could get in) I'd leave it. They'll still be perfectly yummy. Just don't save seeds from those particular tomatos. :)

Here is a link that might be useful: catfacing

I have a lot of catfaced tomatoes this year due to unseasonably cool temperatures during some critical times. Most of them just look a little weird, but will be perfectly edible if they make it to ripening without being ruined by disease or bugs (which has happened to some, in which case I of course removed them from the plant).

A little curious about your wording, are the "holes" in the blossom end more like indentations covered with skin or scarring, or open to the inside flesh? If the holes are open, they will probably attract disease/insects pretty quickly.

When the maters are really rolling in, I'll remove the very small catfaced toms. I leave them if the get any size. Usually the catfaced toms are early ones.

Huh! I posted a reply to this a day or two ago, and it appears to have been lost!

Thanks all, for your comments. After reading flowersandthing's link, I think mine were caused by cool temperatures, but in any case they do seem to be the early ones. Since they've now grown pretty big, I think I'll leave them and cross my fingers; I don't care how they look, as long as they taste good!

Sunflower, the holes look like, well, holes, but only a little deeper than they are wide. They don't seem to be open to the inside flesh, as far as I can tell. I poked a slim twig in, and it went in less than 1/8 of an inch maybe (though I didn't have a ruler with me). So far I don't see any insect activity.

Thanks!
