I don't know what causes it but here's a picture of one we grew years ago.

Keep the possibility of Nematodes in mind. Take one to the local Agricultural Extension or best Garden Center, for visual advice. It's hard to tell without a photo or cuke to see? God bless and help you. : )

It could be a lot of things. Have you checked them for bugs?? You could be overwatering or underwatering. How much fertilizer are you using and what type?? You might want to try Miracle Gro for veggies on them but don't overfertilize. How do the leaves look compared to the cucumbers, are they healthy??
