Green or ripe fruit?

Hard to say without seeing them. But best guess from your description would be Alternaria if talking about ripe fruit. Don't know if it is common in your area or not. Another possibility would be Bacterial Speck or Bacterial Spot on green fruit. Check out the tomato disease photos linked below.

Oh sorry Dave. No pics, as it was from last year. But, it was like a hard black round pinprick under the skin, as if a tiny little bug got right under the skin. But, no holes. Hard to explain. Sort of like a wort, but very tiny. It was present as the fruit formed. Remained as it ripened. It would only be on some fruit, and only one spot each mater. Question, could it have been bugs? I really want to hope not. Thanks Dave..
