Does anyone recognize this disease?

This showed up one morning, about a month ago. The plant was in a pot so I rushed it to a secluded corner in the yard, far away from the tomato garden, to keep an eye on it and see if I could figure out what was wrong. Every time I checked it the streaking on the stem and spotting of the leaves involved more stems and leaves so I lost my nerve and put the whole thing in a garbage bag, tied it up and threw in the trash. I watched all of my plants closely over the last month and have never seen anything else like it. Could this be tswv? Anything else? I appreciate any help I get on this.
