I have had some strange looking tubers over the years. Most of the time I save them and see how they do the next year. A few years ago, my 'Cornel' looked like that. This year, the plant looked great and I see no tuber "bumps".
If i get a dahlia (in the growing season) that looks like it has the dahlia virus, I dig it up and destroy it... you can google for photos of this virus.
I have never stored a "bumpy" looking tuber that resulted in a Dahlia with "dahlia virus" the next year.
