Several of my tomatoes are misshapen. Why?

Question: 

Several of my tomatoes are misshapen. Why?

Answer: 

Misshapen (catfaced) fruit may be due to cool weather during fruit set.  Exposure to 2,4- D or similar broadleaf herbicides is another possibility.  Catfacing is most common on large-fruited tomato varieties.  Affected fruit show leathery scars, bulges, or holes at the blossom end of the fruit.  The incidence of catfacing is typically highest on the early maturing fruit and declines during the remainder of the growing season.
