I hope this grower doesnt mind me using his picture as an example. I dont have such a good pic of my own. I saw this in my own tomatoes at least once this year. What do you think about this? Id say its not typical BER from low calcium within the plant, instead its where a droplet(s) of water were hanging from the tomato, and some of that moisture got absorbed into the tomato? I also had this happen, this (atypical) BER only occured where there was a water droplet hanging on the lowest surface of the tomato for an extended period of time.
Does water hanging on the underside of the fruit block normal transpiration or dilute calcium away from that part of the tomato? This hanging water is a hazard & a half it seems...??
Curious what anyone else thinks.

Should there be a different name for this, like "water end rot" or something?
Thanks to the grower for the use their picture... Just trying to understand what this truly is, not trying to give their post any unwanted attention.

Two diseases come to mind, Anthracnose and Rhizoctonia. Probably anthracnose. Daconil, If organic, certain copper sprays. Discard any effected material to prevent spread. Rhizoctonia also effects roots, with similar lesions on the fruit.

Alternaria would be a third possibility. Phosphite or AgriFos is effective as systemic.

Smart thinking Perriman, yeah it looks like a primary or secondary infection has set in, so its a bit unclear. This is the one that I had what I would label "atypical BER". The tomato didnt lack calcium to the point of getting typical BER, but the calcium was low enough that it was somehow affected by a small bit of external water?

I would call this "water end rot".
In this case there is no secondary infection yet, there are some healthy growth cracks and the tomato may actually make it.
Just thought my fellow tomato growers would find it interesting or helpful to maybe distinguish this "water damage BER" as a separate type of BER.
Good luck with your growing! Brandon

You're welcome. Hope it helped some. This latest pic looks more like BER although I'm not close up. It is mainly a water issue in how much water is overload or underload causing too much stress, therefore water rot or water-less rot. Transpiration mainly has to do with humidity, heat, how the plant copes with excess or lack of. Calcium helps prevent this some as long as it is transported mostly through the roots. One study explained that the calcium mainly needs to be available by the tomato being about the size of a dime and they suggested foliar calcium mainly at time of dime size tomato.
