Some kind of weird rash appeared on the hand of a friend. Well, I bet you've never seen anything like this. And won't, either, cause I don't have a photo of it. :) But here is the description: It's a brownish-bluish discoloration on the back of his hand. It covers the outer-upper half of his hand, up to the middle of his little finger and ring finger, and it's approximately 2 cm-s in diameter. It's round, with a smaller circle of normal skin in the middle (kind of like a fat ring). It feels just fine to the touch, not scaly, not dry or anything.
It looks really... abnormal. Huge homogeneously brown something showing up over night?
Nearly forgot: no trauma or pain, though it resembles a shiner in color.
am really clueless...
