Oral vesicle (hint hint). Blistering vesicular lesion on the hand. No fever, not toxic-appearing. This is Herpes (you may remember dentists getting herpetic whitlow in your studies, which is what this is). Most folks get HSV1 as children, though obviously not all are symptomatic. HSV is a large double-stranded, linear DNA virus.
