Mycobacterium marinum
My hand currently looks similar, albeit more berry-like and purple/white-ish.
Went to a dermatologist and first thing she asked if I had a fish tank -- to which I replied no. Next she asked if I was doing any outside in the garden (!?) -- to which I also replied no. After some more questioning, I mentioned I have a hydroponic basil setup (which is true) and that I more or less routinely dip my hands into various containers of water.
Turns out that changing nutes/adjusting airstones after getting two mosquito bites on my middle finger while cannanapping was all it took. The two "cuts" allowed the bacteria to get through. Me scratching the at the time harmless looking bites didn't help.
Her recommendations were:
1. Clean surfaces of all tanks to prevent future infection.
2. Wear gloves when working with tanks.
So there you have it. A bacteria people who deal with water regularly -- people with fish tanks, marine biologists, swimming pool cleaners, and apparently hydro growers -- should know about.
