Brown indents on tomato?

New to the forum and fairly new to gardening. I have a container garden on my balcony and need help with a tomato problem. I've noticed some brown spots or indents on the bottom and side of two of my tomatoes on an otherwise very healthy looking plant. I've done some research and haven't seen anything exactly like this. It doesn't seem to be blossom end rot as its not directly on the bottom where the blossom would be attached and it doesn't look bacterial. My guess is the damp weather lately. Should I remove these tomatoes? Is this something that will spread to other tomatoes and plants? Is this a fixable problem? I've attached a couple of pics. Thanks in advance for your help!

BER?

Its definitely not BER, and it doesn't look like something that is a communicable disease because the rest of the plant looks good. Sometimes weird things happen when pollination is incomplete and/or, temperatures affect development etc. Catfacing is one such thing and starts when the locules split open when the fruits are little greenies. Your bruising looks to be centered on the locules so I suspect somethng like that is going on. I would toss the fruits that have a lot of it and save the fruits with a little. You can probably cut out the bad locules when the fruit ripens....or I'm wrong and the whole fruit will rot.

That looks like anthracnose to me. It's a fungal disease so spraying with 10% milk solution should help any more from becoming damaged, though the existing damage can't be healed.

Cornell says that Anthracnose infected green fruits do not show spots until the fruit ripens.

While milk works for viruses and powdery mildew, it can exacerbate/induce other diseases such as early blight [Alternaria], black rot and soft rot.

Ah! Interesting. The regularity of these marks were bothering me.
Thanks for the followup, TZ.

Thanks for the feed back. I'm still not 100% convinced as to what it is. My best guess is that its weather related as its been overcast, humid, and stormy for about a week or so. I will most likely dispose of the damaged tomatoes and hope for better luck and sunnier weather for the rest of them.
