One of the things I regularly inspect for is blossom end rot on my medium/large varieties.
It's a good idea to remove any affected fruit so the plant can put its energy into producing fruit that is edible.
Blossom end rot isn't infectious so it won't spread but you may find more than one tomato with this problem on a plant.
It's caused by a lack of calcium uptake owing to cold conditions or dry root areas when the fruits are forming. Keeping the whole of the root area moist is the way to avoid BER but most gardeners who grow using traditional soil methods will get BER affected toms from time to time.
