A 27-YEAR-OLD man went to urgent care complaining of a single skin lesion on his hand. What had started as a smooth nodule had ulcerated and spread in a lymphangitic fashion on his hand. He grew worried when he started to have a fever. The only unusual activity he’d done in the last few weeks was clean out one of his big saltwater aquariums to prepare for purchasing new fish.
