Ok, I know it's not the Biggest Lipoma Ever, but it's the biggest one I've removed in my short career. You probably can't really get the scale from the picture, but it's about 10x7cm. (I didn't take a photo of the incision because, well, it's not my best work.)
The small thing on the left is the remains of a little sebaceous cyst removed from the same patient. I've yet to excise one of those without rupturing the cyst - perhaps I should add that to my To-Do List.
