Zebra
A rare diagnosis when the common one is far more likely.
Definitions
A rare or exotic diagnosis that an over-keen doctor reaches for when the patient almost certainly has the boring common thing. Used as a warning ('stop zebra hunting') and as praise ('she nailed the zebra'). Med students love them; attendings make them rule out the horse first.
The patient with the rare disease itself — adopted as a badge of honour by communities like Ehlers-Danlos sufferers, who got tired of being dismissed as too unusual to be real.
Zebra In A Sentence
Origin & Usage
From Dr Theodore Woodward's late-1940s aphorism to his interns at Maryland: 'When you hear hoofbeats, think horses, not zebras.' In Maryland, hoofbeats meant a horse. The Ehlers-Danlos community reclaimed the zebra as their mascot.
