Is this citrus cancer or black spot?   Treat with copper?  It’s only on two fruits so far that went through but I think smaller on other fruits.  It is almost harvest time

I appreciate the link but nothing really looks like my picture.  Maybe sunburn or windburns?  The tree and my others look great per your advice.  Now this.  Stared as a spot and grew

It can happen from many things. Usually from damage to the peel. No it's not canker. Birds pecking the peel can cause this as well.
