Picture Quiz: Know your enemy
- By: Stephen Goldie, Vincent Smith
A 22 year old man visits his general practitioner for advice on an “itchy rash” which has developed overnight. The young man had just returned from a fishing trip on a loch near the village of Fort Augustus in the Highlands of Scotland, famed for its position at the bottom end of Loch Ness. He and a friend had camped on the shore of the fishing loch. On closer examination the doctor noted an urticarial rash spread all over the man's face, neck, hands, and forearms (figures 1 and 2)--that is, the exposed areas of the body that were not covered by clothing while fishing.
